Soredemo Sekai ha Utsukushii
Watched the anime first and fell in love with Livi and Nike. Manga version is just as lovely. Don't let their age gap stop you, they're both pure on the topic of love (regardless of how mature Livi acts lol).
Hajimari no Niina
unprofessional review but whatever this manga made me cry my goddamn balls off and I loved every second of it. I enjoy both the main leads and the rest of the supporting cast is wonderful as well.
Nekota no Koto ga Ki ni Natte Shikatanai
I love Mikki, but her absolute innocence (pretty much ignorance too lol) sometimes made me worry if things would turn out okay. It did try to stray clear of the melodramatic love triangle though, which was good. Nekota is absolutely adorable, both cat-faced and not. I would love to see more of their adventures in high school and beyond, but without his cat-face, I fear that it just wouldn't be the same!! (Haha) Love them either way and an adorable series that I would re-read any time.
Kanojo Ni Naru Hi Another
Sequel/Spin-off to Kanojo ni Naru Hi, with special cameos from Mayama, Miyashi and Miki from that series.
