noo i think she doesn't want seoin to find out she's the reason Yeongwoon left him , and that his brother was the reason he stopped doing judo given he gave him a permanent damage t his body and that his mom gave his dad the money to shut them up and to split the boys up ...i think thats the reason why she doesn't want them to reconect again

I don’t know tho i think seo-in knows jaewon had something to do with it too some extent. His only reason for approaching yeongwoon in the first place was to bother jaewon, so i feel like he knew jaewon would retaliate in some way. To what extent he knows is still up in the air but I don’t see the mom going out of her way to protect seo-in’s feelings like that. I only see her keeping that information from seo-in now because jaewon is dead and she wants to seo-in him by her side.
Ahhhh it makes no sense now why seo-in’s mom crashed out when she saw them together. Especially if jaewon is dead she probably blames yeongwoon for it to some extent.
