Ng, if that happens to you, well I bet you're going to be like kanghee,
no.
İf you feel insecure you should try to be an even better lover so your partner only has eyes for you or break up if you cant stand you partner anymore

it's not how it works in rl tho

Kanghee sucks, he really wants seonjae back after seeing someone else because he "was lonely uqu" honestly, he's annoying
