I really don't understand Tago's motives or feelings. I get the author has tried conveying it sort of with the flashback to the brother but it still feels unclear and a bit weird? Like it got cute again and seems like he is starting to genuinely like Ogi but that opening to the second chapter still feels like a really weird character insight? Idk I guess we just disregard that as him being a little creepy, horny teenager at first? hm
