Damn, my two go to fluffy novels were already both taken But I'm glad I convinced you, I hope it doesn't disappoint
I wasn't talking about drama, just feel good and pretty sweet romance stories. As far as exciting/emotional content goes, if I recall right both had a bit of it, but imo both also had happy feel good ends. If you're very emotionally sensitive, Itoshi no Karin is probably the more suitable one, as it's a story about pretty much the two main characters only. Koisome Momiji has some unfulfilled romances with some characters, but everyone seems to be (in the end) happy with it and, at least for me, it still left a good aftertaste. Both of the mangas I actually uncharacteristically bought for myself in original language, so I clearly don't feel they were that bad. All in all, kinda hard to elaborate without spoiling anything, but I hope I succeeded. UPDATE: Perhaps the closest relative to Itoshi no Karin could be Amari Mawari, if you have read that one. Amari Mawari is all about a guy who likes cute fluffy animals, and a girl who likes the sparkle of the guy's hair.
