Jisung's in Chan and Changbin's bed, squished between them with all of their legs tangled together. Somehow, in all their years of friendship and then even more years of two parts friendship one part committed relationship, they manage to never make him feel like a third wheel, he's never been an unnecessary extra- it's like those three piece heart necklaces where the outside two pieces can make a heart, and Jisung's the middle one, fit in between to make an even better heart.
