Public

Nico isn't the one to show PDA. Around in public, all you would is a gentle peck on the forehead. On the days when he feels confident, he'll kiss you on the cheek. If he feels threatened or jealous, Nico would kiss you right then and there. But if he's  jealous that day... O h b o y.

Around Friends

When it's just you guys and your friends he'll be a tad more affectionate towards you since you're around friends who wouldn't judge you for it. Doing so, he peppers your face with kisses.

Alone

He turns into a whole new person. He opens up completely and shows a lot more affection. When he kisses you, they would gentle and soft. When he's moody, they're rough. And when he wants you, they're desperate, sloppy, lustful, but overall still filled with love.
