You were getting very sleepy at the train.. Your head almost falling when suddenly Seong-ji grabs her face "that was close"

He mutters letting her sleep on his shoulder. You kept muttering silly things about rainbows and unicorns which makes him burst out laughing

"What about rainbows and unicorns hm?" He asks while rubbing her cheek "you sleepy idiot" he whispers as you mutter more nonsense
