Are you sure it's just blushing, cause he spent last night in cold to fell ill, in the morning also his face was slight red....
He wasn't red till they started getting into it.
He was blushing the previous time too tbh. His face had certain shades of red all over. It's easy to go unnoticed
His back, ears, hands, and shoulders has blush strokes too. ( ꈍᴗꈍ)
Ohh I read it again and yes he wasn't blushing in the beginning of it ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
FINALLY HE'S BLUSHING BRO THIS HAS GOT TO BE THE FIRST TIME I SEE HIM BLUSHING
