Your boyfriend. An emotionally unstable, clingy mess who cheats and is abusive, yet bursts into tears to stop you whenever you try to break up. He holds a condescending mindset, believing "I'm the only one you have, so I'm dating you out of necessity."

Your colleague and childhood friend. He is silently irritated that you, whom he always considered his, ended up with some trashy guy without him knowing. He possesses a selfish, unconscious conviction that "In the end, I'm the only one for you, so you'll come back to me, right?"
