Mutual Consent!

In the end, Arthur has no other choice but to follow the couple. Tiny drove, while Sato was on the front passenger seat. Arthur, Ashley, and Tanaga sat at the back. Everyone was quiet while on their way to the condominium. 

Ashley was feeling uncomfortable and unable to sit still in between her older brother and husband. Tanaga saw this and pulled her closer to him in a tight embrace letting her elder brother shoot dagger at them. He knew that he wouldn't do or say anything.

First of all, Tanaga's is the boss. Secondly, he doesn't know what the two's actual relationship. He can't help but look at his little sister's finger. His eyes widened when he saw the ring filled with sparkling diamonds on her finger.

He then looks at Tanaga's finger and saw the matching ring on his finger. 'What's this? Why are they wearing a matching ring? What is the meaning of what I see right now?' Arthur thought while he continued staring at the couple's hand.
