Basically the same plot with bio kids helping to get a dad and wrongly framed mom back together after years apart. Similar plot with illegitimate sister framing FL. And more similarities.
Both are mini dramas in which a couple breaks up due to a misunderstanding, lies, and scheming from relatives. The FL then returns with a stronger, more jaded personality. In both, one of the parents was unaware they had a child or thought the baby died and discover that they now have a child(ren) who helps brings the two back together.
