Well damn... they took turns stabbing the body. Little did they know forensic can tell those are dealt after the fact.
Anyway, how can two people with barely any money afford to live abroad? You can go to somewhere cheap but you will still need to find a source of income. Kuroko also has a mother she still need to take care of.
I feel like had they just called the police, they might be able to get away with just a self defense charge. Seems like their whole building knows how violent the husband is, and there are likely enough evidence to support a very strong self defense case. If anything, the additional stabbings may work against their favor as they may be considered as unnecessary force.
Onto the next chapter I guess.
