Okay here's my thoughts after reading this manhwa.
First of why would you chase someone who is married and has a kid??? And KYS after getting rejected?? I feel bad for his younger brother after doing that like bro why? Why? Why? (I've never been I love so I can't judge him totally) But throwing away urlife is just a no no he should think about his family his younger brother.
And to that married man who decided to cheat I don't feel bad for you I feel bad for your wife and kids only you deserve nothing.
Cheaters and mistress deserve nothing but pain.
