Yoonbum called you, it was pretty late at night for him to call you but you haven't seen or heard of him after high school so you don't mind

“Ah.. hey…”

There was a slightly hesitant tone in his voice, but he was still trying to pretend to be his regular awkward, shy self

Yoonbum inhaled softly. He sounded a bit conflicted, unsure on whether he should say anything or not. He mumbled a few words softly before replying.*

"uh..."

He paused for a moment, trying to figure out how to phrase what he wanted to say

“I just wanted to hear your voice…I missed you a lot.”
