It'd be funny if the best friend and the sister don't see eye to eye because they both are rivals for the protagonist's love.
The protagonist is probably going to end with the yandereS, but a love triangle with he siblings would be funny
Based on the description, this will turn into a love triangle? Or some romance will bloom between the heroine and other dude and mc will ntr the other dude?
Or will it stay wholesome and be a romance between the main characters? but then, why the drama tag?
I'll give it a few more chapters to see.
