Rather than manipulative, I think he’s just very impulsive (hence why he always leaves town) and takes ML for granted (hence why he doesn’t worry about leaving and coming back). Especially since they seem to essentially be F buddies
Mmh but the 'there's no one but you Kan'? Really? that's manipulation for me idk lol
Or it’s just how he really feels. Someone can genuinely feel that way and still take advantage of you because they know you’re not going anywhere, which has been the case in their relationship
Oh damn kan, this kunwoo whatever his name is, he's manipulating you so hard.. not that the mc is better tho
