Tensei
One Shots of first loves, seems like, going by first two stories. High Schoolers with their gentle stories of romance. First one has a SUPER shy girl and Popular Sportsy Guy. Second has a restaurant setting with a cook and a waitress. This author always has wonderful, lovable characters, and these one-shots make your heart warm with the sweet first loves.

The leads are so cute together: He's the deadpan handsome guy who is super popular but isn't a flirt or a player. She's the strictly-raised, innocent gal with an overprotectivef grandfather (leading to "old people" hobbies for her). Fateful meeting on the train. Adorable progression. Just a really cute shoujo romance manga. The couple reminded a bit of Kimi Ni Todoke's in the sense she's quite a bit like Sawako in terms of naivete and sweetness and he's got that serious handsome thing like Kazehaya. Really would love to see more.
