Ugh! Here we go with the clichéd handsome rival dude. Listen, Blue-boy, it's none of your frickin' business what type of relationship Lee Gigo has with Oh Roji.
Was impressed he didn't get overprotective and gave them space to interact (especially with the it's not illegal comment - heck yeah), then he got on his toes... Cmon man you almost handled that well
Oh well, guess it would be too mature if he acted aloof when the other guy was talking to her.
