the tshirt was the flasback from some other night? maybe. or day idk. haha. but mokyeon was drunk and nanjo was picking him up. nanjo was just telling moknyeon the thing he said to him while he was drunk on that other day. and the shirt is the current time.
I have some questions, how did Nanjo go from wearing a t-shirt to wearing a shirt? And was he standing on that skateboard with both legs (╯°Д °)╯╧╧
