This actually isn't as bad as people make it sound. Especially in the later chapters. He is definitely not a cuck, so get that shit outta here. It's a 5-8 page slice of life, so there isn't a lot of progression that happens. It's mainly about a girl that has liked him for a long time and tries to seduce him passively; she just also happens to be cute doing it. And frankly, his reactions almost seem like an older sibling treating it as his little sister asking for attention. At least later in the story.
I can see the frustration as to why he hasn't even tried to kiss her yet, but honestly, if people can enjoy a female lead teasing the shit out of a genuine loser male character they can at least appreciate the vanilla that this is. All that said, if he doesn't even kiss her or the other girl by chapter 50ish to 60, I will drop it.
