Detectable Rivalry~ Heizou x fem!reader

Birthday Present

Heizou locked the door and you looked around. The room was intricate, small details made your eyes wonder. 'Looks like i need a key..' You crouched down and looked at the opposite door. It had an intricate lock system, the keyhole being an unusual shape. You stood back up and looked around the room. You knew Heizou wouldn't put anything in an obvious place, he knew you too well.

You reached onto a shelf  and felt a small button. You pressed it and heard a click. Looking around, nothing seemed too different - to the average eye. To you, you noticed a leverage on the floor. You crouched down and squeezed your fingers into the small opening. With a rip of the wood, it opened. A small note lay on the floor. Picking it up, you saw a series of numbers.

143

You stared at the number before continuing to look around. You noticed an abacus which took your fancy. Walking over, you saw three bars to it. 'Heizou, Heizou, Heizou..' You shook your head, thinking about him. You squinted and slid the beads across to match the number.

Another click.

You saw a chain hanging from a wall. The wall had a faint line halfway down. You took the chain in your hands and stepped back, the chain almost touching the floor. Pulling on it, you saw the wall open, similarly to a door. Your eyes lit up. You were pretty sure that if anyone else were to get this present, they wouldn't be able to work things out as easily as you.

The door stopped half way and revealed a series of pictures. They were all of you and Heizou; you had taken them with Aether's Camera not so long ago. The photos had a red light under them, signalling they were incorrect. All of the pictures were loose. Upon deciding, you took them off and lay them on the floor. After looking at them for a while, you noticed that each of them were taken on different days, could it be a time order?

You picked up the earliest one and placed it on the first hook. Your eyes glistened when the light turned green. You clapped excitedly and looked back down at the photos. You then picked up what you thought was the second picture. Placing it down, the light turned green once more. You smiled and looked back, two left to go. You remembered taking one of them a few days ago. Picking up the other, you placed it on the third hook and grinned when the light turned green. Finally, you were down to one. Placing it on a hook, a small gap opened in the wall.

A box with a key inside. The key didn't look the same as the one needed for the door, so you looked around for any type of safe. Opening draws and cabinets, you saw a small box tucked away. It took you a few tries but you finally reached into it and grabbed the wooden box. With a click, the key fit. It sprung open and revealed the final key. It's intricate design looked almost like a flower. 'Bingo.' You exclaimed, placing the box down and heading towards the door. You inserted the key and twisted. A final click and the door was open.

The room was pitch black, until a light suddenly came on once you shut the door. There they stood. Yae Miko, Kujou Sara, Aether, Kamisato Ayato with Thoma, Beidou, Kazuha, even Yoimiya and Itto. And in the middle, Heizou. Your hands started shaking, there were a generous stack of presents in the decorated room. You couldn't contain your excitement and ran straight to Heizou, jumping into his arms. He looked startled at first but caught you nonetheless. He spun you round to make sure you wouldn't fall over. when you walked in, party poppers went off and everyone shouted happy birthday.

Before you pulled away, Heizou whispered in your ear. 'Happy birthday Y/n'. The things this man does to you. He made you blush from the exact same words everyone else just said. You whispered back thank you and made your way to the present table. Everyone showed you which present was theirs.

You opened Itto's first, it was a small box with two large Onikabuto inside. Yoimiya's present was a large selection of Dango, all displayed with different colours. Kamisato Ayato gave you an amazing pair of earrings, which were engraved with purple embellishments. Thoma gifted you a new scabbard. It had your initials designed into the leather. Opening Kazuha's present, you were given a Mistsplitter Reforged, a sword which perfectly enhanced your electro energy. You were surprised how he even got this sword. Beidou's present was a ticket to Liyue, Mondstadt and Sumeru. Yae Miko gave you both a large pouch of Mora and a large stack of detective books. Finally Kujou Sara tried to be funny and gave you 'a two weeks paid vacation'.

The whole night was so fun. You ate cake and chatted with every one of your friends. 'I can't believe you put this all together Heizou, thank you..so so much.' You said to him as Kujou Sara and a very tipsy Yae Miko left the building. 'It's not over yet, come on!' Heizou turned off the lights and pulled you out of the door. You laughed and joined up to him. 'Heizou where are we going?' Heizou just looked back at you and smiled. You were pretty sure he was taking you to the infamous Sakura tree, right?

The sky was an electric purple, stars poking out every so often. Heizou instead took you to a different spot. It was very closed off and you could see the bustling streets of Inazuma. 'I did want to show you this at sunset, but Yae just kept drinking and-' You laughed before cutting him off. 'Heizou it's fine. This is perfect.' You smiled at him. His eyes lit up as he looked at you. 'Oo! Right, okay birthday present time..hold on..here it is!' Heizou pulled out a  long, red box from his jacket and smiled as he gave it to you. Carefully unwrapping the present, you slid the lid off and saw the most beautiful necklace.

It was an oval shaped locket with a green and purple swirl on the front. You instantly knew he was referencing your visions. You opened the pocket and saw two pictures. The first picture you and Heizou took, and the latest. The gift was so beautiful.

As you looked up and Heizou, you saw an eagerness in his eyes. He waited for you to say something, anything. 'Heizou this is..this is amazing. Oh my god i love it-' You wrapped your arms around Heizou, pushing him to the floor slightly. You both laughed, but didn't move. 'I'm so glad you like it Y/n..i got it from a market stall in Liyue!' He seemed so proud of his present and you loved it just the same. You sat up to put the necklace on. 'Can you do it up for me?' You asked, smiling. Heizou instantly turned pink but nodded. You placed the locket down and tilted your head. He gently latched the locket together, brushing your neck in the process. The things this man does to you~

Heizou smiled once he saw your face. 'Y/n, i was wondering..well i mean..i was thinking about this for a long time and i completely understand if i've ruined this since Liyue and i'm really really sorry but i wanted to know if..' Heizou looked down while you looked into his eyes.

'If you wanted to be my girlfriend?'
