i’m looking for a yaoi/bl i forgot if it was a manga/manhwa/manhua but anyways...... it was about these two men who loved each other and end up moving so they can marry in a different country. it was preschool teacher x uncle/guardian. the uncle fell in love with his nephew’s preschool teacher. (that’s all i remember from the beginning but....) after a time skip turns out the nephew is in love with his friend back from preschool (the friend is now his step brother) and calls his uncle for advice. (●￣(ｴ)￣●)

i apologize if this explanation is confusing ╮(￣▽￣)╭
