I think it's more like he was trying to respect natsuo's wish to remain friends. That's why he didn't confront him head on about it. It's wasn't him leading him on or anything.
He did, didn’t he? But then why allow Natsuo to make a move on him while he was drunk? It seems like he knew what happened and somehow allowed it.
Did kousuke know that natsuo tried to make a move on him while he was drunk? It looked like he did know but I m not sure about it. If kou knew about Natsuo feelings.. was he leading him on.. on purpose, as he did not want to lose someone’s affection towards him or did he not want to lose their friendship? Which is it? He did accept it at one point to Yuge. But it’s still confusing. It did looks like kou was being greedy.
