Damn, this manga is something else. At the start I was thinking how old it would get just reading about a spoiled younger sibling, but I was pleasantly surprised how deep and heartwarming many of these chapters are. For those who are going the comment section before reading this series, this is a very good light hearted story, which makes you go on lots of nostalgic feels.
10/10 wish I could go back in time before I read this just so I could read it again.
