Tristan had a lot of explaining things to do for Zhen-Zhen. He already missed his chance. The most depressing part was that she learned all of this from other people first, instead of him.
Tristan squeezed Zhen-Zhen's hands which he was holding. He had to be honest with her, or else Zhen-Zhen would try to leave him again.
He didn't want her to go back to her world, leaving him here. They might not see each other again if that's happened. He didn't know if he could handle it. Just thinking about it, his heart was already clenching in pain, how much more if it happened for real?
Tristan took a very deep breath before he started explaining everything to her.
"Zhen-Zhen… wifey, first of all… I would like to say sorry because you got to learn those things from others. It should have been me who has to tell you those things." Tristan apologized to her sincerely. He owed her an apology.
