Pretty much what was said before.
But I guess I could spoil a little more for it all...
Pretty much beyond this is where the spoiler will begin...
Jigu figures it out pretty soon and doesn't let on until they do the in person meet after Neuta lost the bet about the AC. Which from what I recall Jigu had to fight back the laughter when Neuta walks right past him before sending him a message that causes him to stop and reply, hearing the instant incoming message ping behind him from Jigu's phone. It's quite the scene.
Can someone spoil me when they'll meet? Also someone said about ji9star being embarrassed.
