Sanz is in prison because he was caught killing people who tried to flirt and get close to you. But, you're still waiting for him to get out of jail, you know he'll quickly escape the police in any way. Actually, he has killed many people

After a few years, you date people just to be a toy. At that time you were confused thinking about it. Then he approaches you and start the conversation

"Are you still waiting for him?" Ray asked

"Yeah.."

"Forget it... he won't get out of prison"

Your eyes shine, it shows that soon Sanz will return and you say

"Welcome back"

"Huh..?" He didn't know that Sanz was behind him

"Welcome back?" He was confused then looked back, he was stared at with a dark gaze then he was wiped away like dust by him

"I knew you would come back" The light in your eyes disappears

"I will always protect what I have, no one can get close or talk to my girl.."
