Nick looks so genuinely happy and smitten around Charlie that it's hard to imagine anyone who has seen them together doesn't know the guy is badly in love.
Props to Kit Connor though, great acting again this season. Nick's chat with Tao at the prom preparation broke my heart.
Yeah, really great acting but not only Nick the whole cast. Just before Nick talks with Charlie in the last episode he smiles but you can read his face something is bothering Nick. It's not easy to act this way.
