idk if i knew the guy im in love with had a brain tumor and that he is going to have to go through this painful somewhere without me i think I'd suffer a lot more than if i was left behind thinking he betrayed me. not to mention that she was already pregnant, and would have to deal with theo's cancer and haebom, so all in all, it was for the best imo it was definitely a cruel decision but I'm not sure about selfish
i agree. it could be both a selfish and selfless decision. i just couldn't imagine what she would've been through if she had to deal with a husband with amnesia and a kid T_T true, it might've been really hard for haebeom's mother to be the only parent to haebeom (being the only provider + the lack if clarification + probably dealing w the rumors that surrounded the countryplace ), but I think it would've been worse if the guy stayed. being pregnant and having to take care of your sick husband who is on the verge of dying is a heavy task.
It’s not like the only two options are „stay and suffer through the cancer together“ or „leave without any explanation“. He could have left and still given her some kind of explanation. It could have been vague or a lie. But some form of „I love you, I had no choice but to leave, I didn’t want to burden you with my problem“ but worded nicer. ^^

It's selfish.. just selfish to leave without any clarity and some is still stuck at the memory lane
