Choi Ocha

You'd recently graduated from university, and after graduation, you went to work as a nurse at the local children's clinic. Your mentor was a guy who'd been working there for a long time. Choi Ocha is quite attractive, tall, and quite athletic. But despite his appearance, he's very kind to children.

It was a normal workday, and you'd just arrived after examining a child. Choi was sitting with children who had undergone surgery or were in critical condition. You bumped into him in the hallway, leaving the ward with his notebook of diagnoses and other information. His hands and gown were covered in stickers. It made you laugh.
"Hey, Master Choi Ocha. Are you changing your style? " you said mockingly, examining his sticker-covered hands and slightly confused expression.
"I didn't change anything. The kids were given a few packs of stickers! I feel sorry for the cleaning staff already. Everything is covered in those damn stickers. " Choi said with a growl and a hint of irony, and seeing your grin, he snapped back.
If you don't believe me, go check it out yourself. And there's no point in laughing.

(The rest of the action is up to you)
