[Childhood sweethearts] + A male lead who can't face reality and won't confess even though he likes her + A female lead who has secretly had a crush on him for a long time
They've been childhood sweethearts for over a decade. No matter what others say, he can't bring himself to confess first, yet he keeps waiting for someone else to confess. He doesn't know whether he likes her or not, and even now he still hasn't figured it out. It's not that he's afraid, he just thinks it's too much trouble. Time waits for no one. Only after they part ways and stop talking does he look back and remember the "I love you" he never said.
