ML decides to marry her just because she's being bullied and being married to him should be better than being bullied.
After forcing her home to get her things (and the fans over at web saying she should be grateful that he's forcing her *cringe*) They go home. In the next panel they just show up at the official office to register their marriage. It becomes clear that they never even spoke to each other that night or in the car ride about anything at all. To shut up her fussing he shoves a icecream cone in her face. Like thats supposed to pacify the situation. Has she even eaten breakfast?
Afew chapters later.
She sneaks away from school to go to work. That's explained no where. Instead we just see her fleeing school to go to work. You dont even find out that thats where she works until chapter 16 (she kinda just shows up sits behind a desk looks at her phone then ML's-mom shows up). Where she is ambushed by ML's mother who shoves a jade bracelet on her hand. To reinforce that she is modest, she declines and somehow they shove a situation of "eating together brings good bonds so go eat" so they go for lunch without her even explaining to anyone at her job that's where shes going. We dont even see other workers or her explaining that she's late/why. Suddenly she gets a call and has to leave. Mom somehow likes this daughter in law who she has no background information on.
New "plot twist" her ex wants her back, because plot. (I lost a few brain cells reading the comments section of that chapter) And she wants to hide it, because plot.
