Taehyung:

Taehyung is engaged to Rose, his girlfriend and fiancée, being a very wealthy man, nothing was a problem for him except his sister-in-law, who is the younger sister of his fiancée who does not settle for less
Taehyung fulfilled her whims since he met her, why he had a certain joy seeing her happy while buying clothes etc
She was very beautiful so to speak, he had to admit that she beat his fiancée in beauty, but changing the subject he always got nervous when he saw her end up accepting the things that his sister-in-law asked for

sighs looking through the papers, somewhat annoyed as he sits at his desk and office, he hears the door open to meet his sister-in-law's angelic face as she smiles

he giggled and looked her up and down "what are you doing here huh?"
