These people complain about everything but they are still camping here. Also as I read this just now, it seems like Yuu is only acting like an older brother to Tsubaki, and Tsubaki acting like an adult protecting Yuu because he is the reason why he has a scar on the eyebrow which he always fails. This is a slice of life! Y'all just have weird minds and think everything is disgusting!!
This is the funniest manhwa I have ever read especially those scene where fathers and daughters fight at each other.
