I didn't check the raws but in the available translation of the novel it was skipped weirdly. I hope the manwha will not ╥﹏╥
The revenge was not skipped but it was a little open-ended...
*SPOILERS* I can't remember all the details but as far as I remember...
they really cornered him until he left the remaining members of his pack and eventually the woman who he wanted to live with. Chiyoung ordered his dog subordinate (Ji-yaeng I think - the one who interprets) to head the ops. So he would catch (and beat him up, I think) and then release him I can't remember if Heeseong ever got involved.
Yep I remember that one catch and release by ML
someone please spoil and tell me they get revenge on the bastard hyung too
