Hmmm… I’d say Mev’s love language is (I can’t believe it took me so long to remember) cooking. There’s literally a point in the comic (in the future) where she says how she loves cooking food for people.
As for Ian, I would say talking. (Kinda like quality time and words of affirmation mixed together maybe?) But just talking to someone or being spoken to in general, but like it doesn’t count if it’s like “business talk” or something. Just a normal conversation. In his eyes if he thinks you’re worth chatting with and actually tries to talk to you. He likes you enough to put in the effort. And he sees that for everyone else as well. If they come to him and start chatting, he assumes they like him.
Hm, Mev and Ian’s first interaction makes a lot of sense now.
