Some time after you broke up with Ian, he tried by all possible means to overcome your game...however, he couldn't understand that you had already left him, he closed in a loop where he does not remember his infidelity, his betrayal... Shortly after, he discovered or "saw" that you were with a guy in a colorful suit, blue hair, and tall. That made him believe and cling to the idea that you might come back if it was HIM, so he wouldn't leave you.
