kimuchi's manga / #manhwa(19)

why is the step-brother such a manipulative piece of shit? what did kim ho do to him to deserve all of this? is the bro just simply jealous? jealous of what? they're not so different in terms of living environment. he seems like he had a good upbringing & was popular at school too. what else does he want for him to mess up his lil brother's life?

i just can't wait to hear what that exwife did.
