There was a few things throughout but he had confirmation when the hyung changed his avatar to "look like his neighbor"
When Yeong was having a full on tantrum and forced Jigu to invite Yeowoon into his apartment. However, that was when he knew for sure. Iirc, he had his suspicions when Neutaa was talking about the bread he got from Jigu.
Ohhh thank youuu. Last question, how about nueta did he also know?(maybe not?)
He will in S2. Either that or S3 if there will be one. He finds out later in the series is what I'm trying to say.
Okay thank you so muchh
When did jistar know that the hyung in the game is the same? (Sorrymasen for my bad english)
