I think the ex in this one will defy the usual trope. In the latest chapters I'm assuming the woman she ran into is his ex and if anything she seems super cool! It's also said that she's already remarried. I do think this arc will make the fl insecure though especially because of the son not seeing the fl as a mother figure.
Is this now the arc of ex who will make the FL insecure? The ex of course will be describe as your typical beautiful, sexy, successful and very rich woman who's very well suited with ML.
**Assumption**
The arc will show how happy the kid lives with her mother and ML seems to still greatly care about the ex. Everyone will be praising how perfect the family looks like.
Ex will live under the same roof because she's the kid's mother. She'll act like the owner of the house and making it seem like she's back for good and willing to give ML another chamce. But everything she does is just to tease FL and ML bec the truth is she's engage to some hottie bad boy looking western man.

Of course, its better if this won't happen.
