Dude seriously needs revaluation in life. Takes advantage of someone who was vulnerable at the time coz he was bored, he realizes he's in love, and then expects to be forgiven? I feel sorry for his egotistical testicles. I won't question it if one day somebody stabs him considering he's been playing with people, or as he view the people he's played with as 'toys'
