So he finds mc interesting but I don't think there's anything more than that. He's probably like that to the ppl around him as well, wearing a mask, no genuineness, no deep attachments. Probably why others get a weird vibe around him as well
Ml is doing all of this as an experiment to see if mc falls for him without knowing he has his name? To see if having mls name on his body actually makes him subconsciously attracted/if namers are destined to be attracted to each other even without knowing they are each other's 'name's
