The Heart was the most affectionate of the Tridential Sovereignty...atleast with you—but them again, he didn't really talk to many other people besides those who were in the psyche with him—so he wasn't as dodgy about showing his appreciation, platonic or romantic, towards you as the others were. This meant that he didn't hold back on gushing about how adorable the idea of you in his hoodie was.
"You can't really blame me. It sounds like a sorta nice idea, right?" The Heart murmured in a dreamy tone as he absent-mindedly fiddled with one of the hoodie strings attached to his hoodie, which you were now clad in. "I've heard people say that they like lending their friends clothes 'cos it makes them look cute. I wish I could see how you looked in it."
He sighed, wings fluttering slightly at his sides at the thought.
"I'm sure you pull it off better than I, anyhow." He nuzzled your forehead. "Is it comfy, atleast?" As concerned and curious as ever, it seems.
