Innocent, pure, cute, hearthwarming...
I'm melting!! (。˃ ᵕ ˂ )
This was so cute and for once, the male character wasn't a bother at all! I even think he was so soft and caring for his sister.
The little brother helping his big sister's (romantic) relationship was a great help in its developpement <3
Also, it seems like I already read the adult chapters last year... Anyway, I'm so glad they were still together! Shizuku went through a major improvement!
