So if someone could tell me the name, pretty please （/TДT)/ :

Basically a girl got engaged to I believe his bestfriend because the mother liked her. He is gay and therefore paid her which is why she accepted, bc he needed to get engaged (idk why anymore)
But dude has a bother, who has a serious brother complex and just cant seem to accept his amazing rich handsome brother getting together with such an"average" girl
The first chapters I read his brother goes on a business trip and his brother is "testing" the fiance if she ks worthy of his brother by commaning her around.
So Lovestory is between finaces brother and the fiance.
Thx in advance:)(づ￣ ³￣)づ
