ohh the description reminds me of this one: https://www.mangago.zone/read-manga/kijima_kun/
The description is interesting (๑•ㅂ•)و✧
Bls where the character sends love letters to the wrong person and the person has already fallen for the character through the letters and gets hurt when the other says it wasn’t meant for them
