gayay asked a question

so i forgot the title of this one manhwa i read where the fl originally thought that the ml was a girl because he had long black hair, which made him cry. they were both friends for a long time and sometimes the girl would play house with both of them crossdressing, which makes another dude think ml was a girl and fell for him. something eventually happened to ml’s family which led to both of them not meeting again, and they opted to write letters to each other. oh and i think fl’s father was with the ml after the time-skip because they were both sent to war or smth. please give me title of this manhwa if any of you are familiar with it, thank you!
