Bokura wa Minna Kawai-sou, Grand Blue Recommendations
Bokura wa Minna Kawai-sou and Grand Blue are comedy story about a young man who came into an environment full of weirdos. He has to live under the same roof with them. The relationship between the main male character and the main female character is also similar (though in Grand Blue they are cousins, so it's less romantic). If you liked one, you'll definitely like the other.
While Grand Blue isn't really a romance show, it's VERY similar to Bokura wa Minna Kawai-sou in many ways. The biggest similarity is probably their type of comedy, both are very well on the same footing, are insanely well thought & executed. Just straight up a tip; don't drink anything while watching either of these shows, we get jump-jokes in these that will make you laugh like some psycho...you will spill it all out. Another similarity is that the female leads are very similar, hair, personality, & more wise.
MC live in a boarding house away from home with people of unknown backgrounds.
Weird people living and interacting together.
In Grand Blue, Chisa is a Tsundere. In Bokura wa Minna Kawai-sou, Ritsu is a kuudere.
Both are good splice of life.
They both are a good romcom anime how ever Grand Blue is more towards the comedy side while Bokura wa Minna Kawai-sou is more romantic. They both also are very relatable letting u see the feelings inside each character to the point that u might even get abit annoyed when the relationships not going well (Bokura wa Minna Kawai-sou) and normal not so normal college guy trying to live a normal life but had his dreams crushed (Grand Blue)
p.s. These 2 animes are my top few favorite animes i highly recommend watching both ... they have good storylines :D
Nothing more, just chisa remind you of Ritsu.
