Natsuwo

“Why am I getting heartthrob!?” The main character is reincarnated as Satou, an extra character in the world of his favorite shoujo manga. He was able to witness with his own eyes the moment his favorite characters became a couple. However, he witnesses the scene where his favorite character, Shirakawa Fuuma, is rejected by the heroine. Sato is determined to return the story to the way it was and make his favorite character happy! But as they spend time together, he finds himself falling for him... This is a heart-warming love story between a young man who is reincarnated in his favorite girls' manga and the main character of that manga!

"Naive" describes Asahi Unowasa, a student who sits right in front of Azusa Ootani, perfectly. True to the meaning of his name, Asahi is shiny like the sun, and Azusa soon falls for him. Despite logically knowing that he can't be the only person who falls for Asahi, he doesn't like the idea of anyone else liking him either. When Azusa accidentally blurts out his feelings, they go from best friends to boyfriends. Not being able to shake the expression on Asahi's face the first time they did it, Azusa sets out various honeytraps to hopefully see that expression once again.
