Yeah, the dude likes Nagi - he was lowkey smiling in the frame where she was chasing him and his buddy with a stick. Reiko-chan has all the Ara Ara Onee-san moves down pat.
@Hollow7F I doubt it. that's too much a cliche. If I had to guess, I'd say that he blames himself for whatever, while the little sister understood and accepted that it was her wishes. makes more sense considering their encounter wasn't particularly confrontational, and that he was pretty depressed in the beginning.
This is a cute little manga! Is there going to be more? If so I would definitely read it, I’m already going to tell my friends about this manga and tell them to tell their friends and so on and so on. Please make more Master-San!😁
