Kabe no Naka no Tenshi
An artist paints a mural of two angels who come alive at night. If a painting falls in love and is loved in return, it's said they can become human, but since no one seems to know for sure, there is the fear of no longer existing. About love and faith. (This story is two love stories in one.)
Sorenari ni Shinken nandesu
Oosawa, a single father struggling to care for his young daughter, accepts the kindness of a customer when she falls ill. Yoshioka is a promiscuous man who is open about his interest in Oosawa, which he doesn't return. But the more time Oosawa and his daughter spend with him, the more things begin to feel like family. A slow-burn love story with a delightful child character and happy ending. I loved it.
Only You, Only
A gay man falls in love with his company president's son, but when the president learns of their relationship, he undermines it, coaxing his son into an arranged marriage. A realistic, mature love story that ends well and happily, with incredibly touching moments - both happy and sad. I cried quite a bit, but the conclusion has me smiling. This is JUST as lovely and touching on re-read and they buy a car! ETA: I bought the manga since I've re-read it so many times.
