Later that night - Ruby Casino -
The plan was simple. He would lead her to the private room where his friends were waiting, and then one of the staff would come in and say a vital guest is waiting for him. He would leave for a few minutes, and by the time he returns, they would have given her quite a fright.
This is very risky, considering her background. But Sano knew he would have to take the risk. If he isn't careful, somebody could snatch her away from him.
Sano never considered this before, so at the start of their relationship, he was very sweet. But now that they have been dating for a while, Sano showed his true feelings. All the frustration he held back is spilling.
"I have to say I didn't know Sano was dating such a cutie."
Sano chuckled. "Hmm? Whose girlfriend are you complimenting? I admit that she is gorgeous. But don't jeer at her."
"Look how possessive he is."
"Sumire-chan here."
I didn't intend for this past arc to be long. I just wanted to show a brief glimpse of Sano's behaviour back then. What happened in the Casino after Sano stood up and left, I will write in more detail with Sumire's POV later on. But I will keep it "short" and brief, since it's an incident that traumatized her.
