This is just my opinion though
I also had the same idea. I just hope the author consider this type of ending so that it can also have a twist or a different ending unlike other common stories u find where the mc always ends up choosing the 1st ml. The mc should also consider his child's future and well being, than having the white hair guy as his partner. Sometimes I wish that stories like this think more logically tbh, because in the end of the day, if he are financially stable and has a husband that had a well paying job, you can pretty much live a good/normal life until having a drug dealer as your partner. But who cares, it's just a fictional story LMAO
I want the father to be the prosecutor because realistically he can provide the mc and child with financial security and a stable home. The prosecutor also definitely doesn’t seem like an abuser and he’s also ready to take responsibility. The other guy may be fun and lively but he’s also an exconvict and a drug dealer that’s not exactly what you want in a child raising environment
