MTL - The Apocalyptic Master of Synthesis - Chapter 532 The heart of the city is in hand (subscription required)

After a night, surprisingly I acquired a husband!

Well, the fact is that after a one-night stand, I unwittingly signed a marriage agreement.

There isn’t a bad in-law relationship but instead a mother-in-law and daughter-in-law alliance.

The purpose of our alliance: Make my husband interested in women!

Frankly speaking, a man who isn’t interested in a woman … is he gay? Having a husband who is suspected to be a gay, I will fight for him and not let him go astray.

So I raise my eyebrows and with a wicked smile: My dear husband, wait and see how I am going to teach you to be a real man!
