This is beautiful, i binge-read it in one day and every chapter was fun and fluffy.
I really really loved it, probably because the character's dinamic resemble the relationship between me and my gf.
I'm wishing that the author makes a married life version. They can still have a pseudo harem. He did after all, in the end accept them all, right? Seki-kun and Takagi-san has their spin-offs where they're married. I want this to happen too.
