The reader is Totoko's Twin sister.

I was in my room brushing my hair out as I got ready. I was going to surprise my boyfriends and visit their home today. Who were my boyfriends? The Matsuno brothers. It was a surprise to many when I asked them out. Mostly because my sister seems to hate their guts. Yet she loves their attention. Well while she hated them and was mean to them. I loved them and treated them properly with kindness and love.

Now they were my boyfriends of 2 years.

I got up and turn to leave my room when I saw my sister leaning against the doorframe. "Going to see them again?" She asks and I nod before leaving my room with a smile on my face.

"You know they don't really love you?"

I froze and my smile drops as I turn my head "What?" I ask and she nods "It's not you that they really love. They only "love" you because you're my twin." She says and I frown "Really? You are unbelievable." I say and she hums "Think about it y/n. They chased me for years and always gave me attention but as soon as you confessed they suddenly loved you?" She asks and I nod "it's possible." I say and she shook her head.

"So naive. They are only dating you because they couldn't get me...that or they saw a possible opportunity to lose their virginities." She says and I glance away "face it y/n. You're just a second choice." She says and turns to walk away. "Although there is a way you can test if they truly "love" you." She says and I look up with a hum. "What?"

I look up at the Matsuno house with a sigh before reaching my hand up to knock. Before I could the door was opened and I was met with Karamatsu. "Hm? Oh hello y/n. What brings you here my dear?" He asks and I smile before sighing. "I need to talk to you guys." I say and I saw his face drop slightly. "Oh? Are you okay?" He asks reaching out and I nod with a hum. "Can I come in?" I ask and he nods before letting me in and leading me to the living room where everyone else was.

"Oh hi y/n, didn't know you'd be visiting." Osomatsu says and I nod before clearing my throat. "Yeah I have something I need to say." I say and they all nod while Karamatsu sat down at the table beside Choromatsu. I rub my arm and glance away while I bite my lip. I look up them to see them all looking at me. I took a deep breath before I say it.

"I think we should break up."

I saw all their faces drop at once. They all stare at me with blank looks before they became looks of devastation and heart break. "W-What? W-Why?" Osomatsu stammers out and I glance away. "D-Did we do something wrong?" Choromatsu asks and I sigh as I rub my arm keeping silent. "Y/n. Please. Say something." Ichimatsu says but I kept silent.

I jump when a hand slams on the table. "Say anything at least!" I turn my head to see Karamatsu close to crying. "I don't mean to yell. But if you're serious please at least give us a reason." He says and they all nod "it would kill us to not know." Todomatsu says as he puts his phone down. I hum as Jyushimatsu took my hand in his.

"Y-Y/n-chan. P-Please." He says with a slight whimper. I sigh and glance down. "...it's because I don't know if you guys really love me." I finally say and they became silent "What?!" They all shout making me flinch

"What would make you think that?!" Osomatsu says

"We tell you how much we love you every minute of everyday." Karamatsu says

"And we show you whenever we can that we love you so much." Choromatsu says

"Not to mention the amount of time we spend together." Ichimatsu adds

"Yeah! We love you so much y/n!" Jyushimatsu says while hugging me tight.

"So why would you possibly think we don't love you?" Todomatsu finally asks and I look down with a blush. I shook my head and sigh "I'm an idiot for listening to her." I say and they hum before they narrow their eyes. "Totoko." They all say with disgust in their voice. They all got up and move to hug me.
