minor? spoilers for those who haven't read to ch-150+ so don't read unless you want spoilers

I think after whatever happens in the next 5 chapters i feel like Haesol's mother would make an appearance at some point where she moves back and then Haesol most likely moves out as her aunt or mother told her to keep the house in a clean condition where she could move out quickly if/when she moves back so that there's no trace of her being there because she said her mother could come back with her new family at any point.

i doubt that its just skipped over and they also mentioned in the last 5 chapters that Yeonwoo was thinking about moving out to dorms or something or they could also end it where Haesol and Yeonwoo move in together once everything else has been concluded
