Onii-chan!

A man in a maroon shirt sits at a table in an office or classroom, holding a pink laptop, then opens it and closes it repeatedly while looking forward. To his left, a woman with glasses rests her head on her hand, looking down at her phone. In the background, two other men sit at a table, one looking at his phone, the other looking forward. The scene is set in a room with white walls, fluorescent lighting, and a red ladder leaning against the wall.
