Read chap 13 again and you'll know why
because the mom said she would kill him and his mom...? no way...as if the mom would be able to fight against doha on equal terms...
Well the mom doesn't know about doha and the ml is unreliable, yes he says all those things but we all know what the price of that is, maybe the mc being with doha would be worse than with his step brother and his mom. Remember the first chapter started out with the mc running away from what I presume a toxic relationship
wait...I totally forgot about that first scene... o.o
Why go back? Might as well stay there instead of being locked up and trapped..
