Bro it's honestly so damn good. I read it because I got sick of being shown ads of it on social media but god I'm so glad I read it. Rather than a "romance," it's more about the growth of these 4 characters at the time when all their lives intersect with one another's.
Obviously yeah there's romance too. But the friendship!! The youth!!! The jokes!!! The goofiness!!! It's!!! It's so good!!! It is so so so good, and I really think WEBTOON should like license it in English too because man. The world is missing out.
Also if I had to say "similar series"… Kimi to Boku (except K2B has less romance), Horimiya (MANGA),,,, and honestly any series that fills you with a nostalgia for a highschool life that you may or may not have actually experienced, man. These kids. I love them so much.
PS: Added a description for the series because I just love it. It's more or less a translation of the errmmm right, the LINE manga, I picked the description from the LINE manga app and just translated it. If some group chooses to pick this series up, feel free to change the description as you may, I really do not care (๑•̀ᴗ•́)و✧ Just do these kids justice if you do pick it up because god I adore them.
