The challenge was like: You just won in Koshien and you give like a pick up line to say to your girlfriend. I think he said *It's going to be a homerun tonight* I just read it somewhere so it might not be correct
i think it's "let's go full set game(round) tonight too" ( ͡° ͜ʖ ͡°) btw pick up line to your girlfriend who is waiting you in front of your house after play full set game in koshien
