Kieta Hatsukoi (2021)

Aoki has a crush on Hashimoto, the girl in the seat next to him in class. But he despairs when he borrows her eraser and sees she's written the name of another boy—Ida—on it. To make matters more confusing, Ida sees Aoki holding that very eraser and thinks Aoki has a crush on him!

When Kosuke was 14 years old, his mother died. As a young gay person, he spent his adolescence in a rural village and suppressed his feelings. Now, Kosuke is all grown up and he works as a fashion magazine editor in Tokyo. He meets Ryuta, who works as a personal trainer. Ryuta's mother raised him alone and he is close to his mother. Kosuke and Ryuta become attracted to each other and they sometimes spend time with Ryuta's mother. Kosuke is happy to share time with Ryuta and his mother, which makes him remember his late mother. Kosuke and Ryuta make an appointment to go for a drive together, but, on that day, Ryuta does not show up.

Kieta Hatsukoi may be a bit more on the fluffy and comedic side of bl, but both of these Japanese series focus on the blossoming love between high school boys. They also both incorporate heart-warming and emotional moments that are sure to keep you invested in their journies as couples.

lgbt high school love interests who have a silly misunderstanding about each other be the main premise that kick starts the show (and both are live actions from manga)
