Lost Boy (Patreon)

Ignis's 'prompto is being neglected' senses were tingling. He's been looking kind of wan when he was hanging out with the prince so Ignis using his...not so legally acquired key to Prompto's house lets himself in to make sure all is well.

Spoiler: All is not well.

If the dictionary had images this would be the one to go under loneliness.
