Often when you see an angry/struggling character in stories like these, the emotions can feel lukewarm, but that last scene definitely made him look a bit unhinged.
@KingE Hmmm.. have you not read any korean modern/fantasy monster invasion manhwa previously? Mum is 'sick' is the boiler plate template side plot, alongside ridden in debt, father now where to be seen and not to forget mc either being the eldest with younger sister or just only child.....
I'm still waiting for a title with mc having healthy present parents, multiple siblings and mc is neither the eldest nor the youngest, sigh.
