Its a Japanese Yaoi and last time I checked, it was years since it had been updated.
So its about high school guys who grew up together, the seme is gay and started crushing on the uke since they were in middle school after watching him do sports. The seme has short blonde/spiky hair and the uke has long/black sleek hair with a part down the middle.
The seme becomes kind of a sex pest and keeps begging the uke to go out with him etc. even though he wasn’t interested. There was even a scene where he licked the uke’s teeth. And I can’t remember clearly but they come to an agreement where they would date for a year and if the uke still didn’t want to, he’d stop pursuing him.
Eventually the seme started going on hook up apps and started having sex with random people, settling on this guy that looked similar to his crush. And then near where the end of the manhwa stopped updating we find out the uke is asexual? because of what happened with his mom. Idk if it was abuse or if he was sexually abused by his mom but that was the reason sex repulsed him and why he never did it with his ex-girlfriend.
Please please if anyone knows what I’m talking about please let me know!
