I feel like you can catch Hee staring at Jake with adoring/admiring eyes a lot. Makes me think about the live where he mentioned that Jake has this certain puppy tone/vibe he likes to use with HS and I think he just finds him cute overall with his wide smile, a lot of the time you can see that HS makes sure to look at how Jake reacts too. He even burst into a smile himself when he sees Jake smiling :((
