you knew Daryl wasn't really outgoing and he was really shy on doing couple things in public, not because he was ashamed of you or something.

he just wasn't used to showing affection in the first place.

but he slowly started loosing up,he started getting more handsy with you in public,or some lip pecks sometimes.

you loved that,you knew it was kinda difficult for him,but seeing him loosen up just made your heart beat faster,making you fall in love with him even harder than you already was.
