Not sure if that's the one thoo since you mentioned it's over 15 chapters.

lost this manhwa i was reading.
its about this uke who's really pretty hes so mesmerizing who legit no hoes but goes to this dinne or smthing and the seme goes up to him taking about needing advice to pull an the uke with no experience at all pretends he does and acts like he knows how to kiss and all.. its still pretty new with like 15-20 chapyers i think.
its been a while since i read it so i may have said some things wrong
