Gu Jin is a straight person, really straight.
In the eyes of his friends, that fellow was a topic-stopper. When all the brothers went out to find him a wife, he ended the fruits of the brothers' hard work for many days with just one sentence.
Gu Jin: From now on you will be my biological sister, I will protect you!
Brothers:…
We are looking for a wife for you, but you are looking for your sister┭┮┭┮
Intention: In this glass time, waiting for the wind, waiting for the rain, waiting for you.
