A good romance doesn’t have to have drawn out plot or hundreds of chapters until a confession. This is peak.
Ig its because the artist is the same but I found myself comparing the characters here to Yuragi-sou no Yuuna-san. Katsuragi looked a lot like the MC in Yuragisou, Sana looks like Yuuna, Nana looks like that ogre girl with pink hair, and Riko looks like the MC’s little sister.
