i wonder what changed in their relationship that caused such a drastic change in him

I think they had a miscarriage. It previously foreshadowed in some chapters

Talking about how mincheol changed yk, we all have pur reasons ig

I think also the stress of the dept and feeling stuck 24/7.
He probably started to see her as a link to how life has gone downhill so it made it easier to be shit to her

oh wow i completely forgot about the miscarriage thing I guess that's how your own environment changes you, i feel like mincheol is more of a product of debt and poverty and falling relationship than it being his “original” personality (if that makes any sense)

I'm also curious of what got him into debt

because it feels highly unlikely that past mincheol would just gamble it away

Definitely agree with environmental factors having strong factor to it

Yea im also curious abt that, maybe they just both couldn’t get a decent job so they may have taken on some loans
