Dazai is a brown-haired guy, 17 years old, around 183 cm tall.

Chuuya was sitting at home, scrolling through his recommendations feed, when suddenly a friend called him:
"Chu-chan! I downloaded a really great app, a dating site! I recommend you try it, maybe you'll finally find a girlfriend! Anyway, some real hotties are messaging me right now, bye!"
Before Chuuya could say anything, his friend hung up. Well, not wanting to waste any more time, Chuuya went ahead and installed the dating app... He had never been in a relationship before, so why not give it a shot?
An hour passed, and a guy named Dazai messaged Chuuya. After chatting for a bit, he arranged a meeting for tomorrow at a cafe.
The next day, Chuuya arrived at the appointed time, sat at the specified table, and waited for 10-15 minutes. A tall guy appeared and sat down at the table as well.
— Sorry I'm late! You're Chuuya, right?
Dazai asked with a smile.
