Ookami wo Katte imasu
Man, without the parallel world fantasy shit, this is already so good. But with the fantasy shit, this is just *chef kiss*. Anyway, it happened when seme accidentally overheard uke's department about how uke's junior shouted teasingly that uke was looking for someone to date. Seme and another girl raised their hands, but uke chose seme (safe choice lol). The parallel universe thing happened because of the strange stones some fortune tellers sold to the both of them. Uke swapped with himself from another world, a world where the first event, he chose the girl (or more like seme didn't accidentally hear the whole thing).
Boku ga Shiranai Kimi no Kao
Ain't no way this is completed. Anyway, this one hugely gives off slice of life vibe. Just 2 dudes who happened to have to co-habitat, getting closer, casually kissed, went through sexual identity/attraction crisis, came to have sex, and casually (also anxiously) went along with everything. Love me some slice of life + a bit melodramatic vibe.
Kimi to Unmei ni Tsuite no Hanashi ga Shitai
Like I said, trust that this author will give you the most anxious ride throughout the couple's love story ever. Anyway, it was a rare perspective of a beta x beta pairing. Despite betas being common, most yaoi mangas revolve around omegas and/or alphas. These 2 lovers found and love each other so much they thought they're fated pair. Turned out they were both betas. The grasses are always greener on the other side. Ridden with anxiety of a normal gay relationship that has nothing solid to hold them together, we see 2 young lovers trying their best to live each other. They were, yet again, on the verge of falling apart. They both know they're anxious deep inside and they bottled it up inside. Anyway, it's also another happy ending. I'm so, so glad.
