yeah, it didn't seem like he was jealous so maybe he just... admires their relationship.. and wanted to mess with them.. Ive seen that happen a lot
Yeah, I feel like he's just curious about them and trying to test the waters to confirm his gut feel about the relationship between the mc and love interest.
If the misunderstanding is cleared up, I feel like he will be one of the trusted friends of the two, who is willing to lend an ear whenever they have love troubles.
But then again, that's just my guess because I'm biased towards the guy. I really like his vibes lol.
Guy just really loves their company and food. He's not really into the mc as a lover material, but as a friend. He just gives off that type of vibe. I hope my delulu mind is right.
