After school, you, your friend Eun-byeol, and your boyfriend Mu-sin found your other friend, Sa-gang, painting the foundation of one of the schools' fences. It was a job she was offered by the art teacher. After a small commotion between Eun-byeol and Sa-gang, the three of you began helping Sa-gang in painting.

It was quite peaceful, the scent of paint lingering in the air while the four of you gently rolled the paint rollers along the wood, it was calming. Until Eun-byeol accidentally splattered a small amount of paint onto Mu-sin's arm. He gave her a look.... and as she looked back at you and Sa-gang, she accidentally got paint on you and Sa-gang as well-

Well, a paint fight began. The three of you chased Eun-byeol, trying to get her back for spilling paint on you three, while she was trying to splash you guys with the pain bucket to stop you. Eventually, it became more of a battle Royale, which meant you each attacked each other instead of the three of yiu ganging up on one-

At one point, Mu-sin had been targeting you since he loved teasing you, of course, so he ended up grabbing you and pulling you closer to him, getting some paint on you. In doing so, he was... smiling. Widely. Brightly. He only did that around you. He let out real laughs as well... of course, Sa-gang and Eun-byeol heard this, and Eun-byeol pointed it out.

Eun-byeol: Look! Mu-sin's smiling!! Mu-sin: Looks up. His smile fades as he slowly let's go of you. Sa-gang: Yea.. it's a little strange to see you like that. (Y/n): uhh.. it's only natural.. isn't it? Sa-gang: He's never smiled aroud us before. Gestures to herself and Eun-byeol Eun-byeol: ...do it again, Mu-sin! Smiles. Mu-sin: ... looks away.

You started to feel a bit concerned. You onew he only acted like this around you, so you knew that he thought he had done something he wasn't supposed to. Now, it was an awkward silence... leaving Eun-byeol curious and wanting to see Mu-sin act giddy again, Sa-gang in shock, you with concern and a bit of seriousness, and Mu-sin feeling embarrassed but overwhelmed at the same time. He kept his stern look as he didn't make any eye contact with the three of you, continuing to remain silent.
