For those asking why Mincheol have no idea where Haesoo works, its because he didn't care. He only know that Haesoo is a "pathetic" woman who works multiple job and yet can't purchase a decent underwear. He only knows that Haesoo works to the bone just to come home to that tiny cold basement. He really doesn't care about her at all. He didn't even know that Haesoo was sick.
If I'm not mistaken, there was a scene in the earlier chapters wherein Mincheol was I think irritated when Haesoo works multiple jobs a day and she didn't give him attention
Finally, a great story after a while. It's like a pallet cleanser
