I think it's just because he reminds him of his boyfriend. He isn't actually in love with him but the reason why he feels so guilty and feels like he is cheating (even when he isn't) is because of how he feels when someone identical to his boyfriend compliments and flirts with him. It's understandable why he'd feel that way
Did he blushed when he called him cute or am I overthinking PLEASE TELL ME IM OVERTHINKING BRO
