I can't say I enjoyed this one that much. Everything just felt a little off. The early chapters felt rushed, like they ended too soon and didn't explore the scenes they set up enough. The jokes were not very funny. I like the character designs and the concept, but most sweet scenes are either interrupted or abruptly end before coming to their full potential. The final arc was very annoying to read. The big sister, the guy's complex and past trauma related to his stature, the ridiculous "test" and the family member gauntlet (it felt so silly and unbelievable), it's all shoe-horned in at the last minute. That kind of finale works if you build up to it, but there's barely been any hint at him having a serious complex about his size up until the last arc. Sure, he complains about it a little, but not the point where it seems like he's genuinely afraid of getting into a relationship. In fact, everything seems to be going swimmingly between him and the kouhai most of the time. It's not the worst manga ever, but it frustrated me so many times while reading it.
