Nirameba Koi
Loved it. I tend to enjoy delinquent and "scary" face but sweet guy stories, so this was right up my alley. Shima is drawn to Ryuu even though he's constantly being glared at and Ryuu isn't exactly good at communicating. As he gets closer to him and falls in love he realizes that Ryuu is a good guy and unintentionally glares to cover up his embarrasses face. This was super adorable and I loved it. I would love to read a spin off about Ryuu's brother, too.
Hachimitsu Darling
There's something really great about this manga. I really liked the gradual development of their relationship and that they didn't hop into bed with each other thoughtlessly. This was about a guy who adopts a stray kitten and when he has to go to the vet because it's sick he's offered a live-in housekeeping job.
Kamatte Kawaii Hito
Really cute. Guy wants to take a girl to a cat cafe but he's afraid of cats so he makes himself go ahead of time to overcome his fear, but while he's there he becomes close to the a worker at the cat cafe. When one of the cats suddenly gets sick he finds himself caring more about the distraught worker than his date. Cute and amusing, though the sex is pretty much glossed over (boooo)
Kuroneko wa Shippo de Amaeru
Sakaguchi is an author who comes home one day to see his neighbor's high school son, Kazuya standing outside his apartment with a kitten. Sakaguchi lets Kazuya and the cat come inside his apartment and when Kazuya explains that his mom is allergic to cats he offers to let the kitten stay with him. Kazuya visits the kitten often and eventually confesses that he likes Sakaguchi. Sakaguchi is drawn to Kazuya, though he feels some guilt about their age gap.
