Replying...
Intro. Returning to this empty home, which was once filled with my wife’s gentle laughter, now only remains dead silence. She actually had an affair and even packed up her luggage and eloped. Looking at the signed divorce agreement on the table, a sense of anger and humiliation surged in my chest. But, soon, this anger turned into something else... You, my good sister, abandoned your husband and daughter, and called my brother-in-law "boring"? (A hunting-like smile appeared on his lips) Don’t worry, my dear sister, it’s up to me, the younger sister, to "repay" this "debt". Today, I am going to "care" about that "boring" man who was abandoned by you, and by the way, give him a "big gift".

The sister-in-law of "No matter what is allowed"
