"Obanai, please... kiss me." Mitsuri begged for more of his love, tears shedding down. Obanai was stuck between the love of his life and the fear of rejection. He looked away, leaving her speechless. "I-I can't.".

Obanai removed himself and stood up, leaving her heartbroken. His body heated in a familiar feeling of pleasure, and his heart beating faster than usual made him think he too would awaken his mark from how close their bodies were. Her beauty could always send him spiraling into a fantasy he wished he could express to her, but maybe it would be a mistake. He had chickened out and was too nervous to make the first move to the woman he loved.

"Iguro wait" Mitsuri stood up accidentally dropping her cup. She took a few steps forward, extending her hand to reach him. "I'm sorry, I should have asked... I didn't mean... I just wanted to know how it felt to be kissed by someone I love." She pulled her hand close to her chest and looked down.

Without a word, they stood there in silence again. Mitsuri's eyes started tearing up as she tried her hardest not to cry, and Iguro was holding his face in his hand, trying to control his urges and find any excuse to cover his behavior.

"I should go." Iguro took a few steps forward, not realizing Mitsuri running his way and wrapping her arms around him, hiding her face on his back, and pulling him closer. Iguro stood frozen, unable to speak from shock.

"Obanai, I'm in love with you! I wanted to wait till after our battle with Muzan to confess my feelings, so there wouldn't be anything holding us back, but it seems no matter what, something always gets in our way." She said as she clenched her hands onto the front of his kimono.

"Even if you reject me, I'm still glad I got to express myself. I can die knowing that I -" And without another word, Obanai turned around, already removed his wrapping away from his face, exposing his snake-like scars, grabbed her face ever so gently, and kissed her deeply. If words were hard for him, then his action was the next best thing.

Iguro couldn't contain himself anymore. Years of loving her came all at once, and Mitsuri was not going to push it away, nor were her fears of ever wondering the feeling of being loved. She knew for a while how much he actually loved her, but she wanted to wait until he told her himself. He held her waist close to his body, leading her to wrap her arms around his neck.

"Mitsuri... I love you more than anything, and if I could, I would take this curse away from you and have you live the life you deserve. With someone who can give you all you wish for. Mitsuri, I can't give you—"

"Then have me now. I know I can't be a wife or a mother... and I know I'm either going to die in 6 years or by the hands of Muzan... I know I'm not strong like you." She buried her face on his shoulder. "But if we can just BE together till then, I'll die knowing I was with you, Iguro." He stood there quietly holding her tightly in his arms while looking at the spilled tea on the ground.

'Was this right? Could I make her happy? Even if it's only a few months? weeks? Days? It feels like our days are coming up, and I wasted so much time to tell her how I feel. I could have been her boyfriend, her husband, or her light. She could have been my wife, my world...'

Iguro didn't know what to do. He wanted to show her what it means to be loved in every different way, but what happens if tonight's the night they fight Muzan? It would be better if it was morning time and there weren't any demons around, but his heart spoke more than his head. He had to do it; he had to take her right there, right now.

"I know it's traditional to be wed before laying in bed together, but I want to at least control this part of my life. And all I want... is to be yours, Obanai." How could he deny that? Her words struck his heart, as he also didn't believe he'd survived this battle. He could feel her shaking from how cold it was outside, and he finally made up his mind. He knew what his heart wanted—to make love with her—but one thing was certain: he was in love with her.

Stepping back a bit, Obanai caressed her cheeks and leaned in for a kiss. Unable to stop to breathe, their kiss became more intense and uncontrollable, and after a moment of their tongues dancing against the cold wind, Mitsuri was able to break away. "Obanai, I can't stop. I want more." She begged as he sucked on the bottom of her lips and licked after. With the simple command "Let's step inside," Mitsuri obeyed.

Later on

As the night got colder, their bodies got closer. Iguro couldn't stop, and neither could she. Mitsuri sweet moans echoed throughout her entire house as Iguro went down on her, tasting every bit of her sweet juice and not wasting even a drop. Mitsuri couldn't help it; she ran her fingers through his jet black hair and slightly pushed his head lower as his tongue alone had made her cum twice in a row. The house was quiet and all to themselves as the kakushi's stepped out for the night to give them privacy after hearing a couple of her moans.

"Obanai, wait, I'm going," she pleaded, biting her bottom lip, holding back from cumming a third time.

Obama lifted his head up and smirked at her as she caught her breath. He sat up to tie his hair up again, all while Mitsuri admiring his body. It was her first time seeing his body without his uniform, and even though she knew he would be fit, imaging it was different from seeing it up close. His slim-toned body, the way his muscles were defined, his abs, and the cuts he gained from previous battles. She never thought she would ever see her best friend in this way, but deep down, she craved it. For a long time, she craved the feeling of being touched, to be loved, and with a small image of what she could have with him, her imagination grew more and more; she craved him.

Still tying his hair, his kimono hanging low around his waist, exposing his Adonis belt, and with any moment his package would pop out. Mitsuri covered her face and slid a finger slightly to the side to see if his kimono would fall, and yet nothing. Iguro noticed her peeking and looked at where she was looking at and chuckled. He slowly hovered above her and looked into her eyes and gave a warm smile, forgetting that his scars were exposed, leading his insecurities to creep in.

While looking into each other's eyes, Iguro placed his hands on her knees and slowly spread her legs apart, exposing her lower area. He pressed his tip against her opening and slid half way in. Mitsuri tilted her head back and let out a sweet hum as she felt a bit of pain. Feeling his hands shaking and his hair falling down again, his insecurity came back and hid his face again so she wouldn't see his snake-like scars. She reached up and slowly touched his scars until she reached his lips. His scars were there, but all she could see was him. He was beautiful. His two colored heterochromia eyes, his sharp jawline, and his soft lips. The scars didn't phase her, but she could see the fear in his eyes. The embarrassment, the trauma, the pain he's felt for so long as he avoided eye contact.

Before she could ask, a cold wind blew out the small dim candle where Kaburamaru laid next to, to keep him warm, with only the moon lighting up the room.

"Hold on, let me," Mitsuri tried to get up to light the candle, but Obanai pinned her back down and hid his face more with his hair.

"Don't. It's better this way." He tried to proceed.

"Obanai, wait, talk to me; tell me what your feeling right now. Who did this to you?". Mitsuri cupped his face, but he pushed it away, stood up, dressed back up, and walked towards the sliding door. "I can't do this anymore.".

"No wait, Obanai! Please!" She stood with a blanket to cover her naked body and ran to him only to have the door slam shut in front of her, leaving her shocked and terrified. After a few seconds of silence, she fell down to her knees and cried out loud, so loud that even Obanai could hear from afar. "Please... don't leave me, Obanai," she whispered to herself without realizing Kaburamaru slithered next to her, rubbing his body against her thigh to comfort her.

Obanai POV

"I can't... I can't. Why did I think this would work? Why did I let my guard down?! Why did I think she wouldn't ask? For just a moment, I thought I could go through it without her asking, but I pussycat out of it! She was right there... she was mine... why.. why?!"

Obanai thought to himself as he speeded his way back home. Reaching for Kaburamaru, he noticed his snake was not around his neck.

"DAMN IT!!!" He hit the stone wall beside him as he forgot to pick him up from near the candle, and now he was there to deal with his own anxiety without him.
