Bro everyone is complaining that this chapter is NTR, but no one is officially dating Jioru. However, poor Minami. But I'm lowkey not sure if the woman was just some older woman or his (step-)mom LOL. I doubt it's the latter.
minami definitely likes his brothers wife cuz in one of the chapters where the cafe owner is drunk he said that he looked like his older brother or sum
....these...probably gonna ended up with Jirou and Akari together in the end while Shiori probably had to give up on him and ended up with Minami....dude seem like a cool guy who doesn't mind being treated as a secondary option lol
