[ Xiao lets out a quiet laugh at Haruka's empty threat, but when he looks at Haruka's expression, how he's trembling and looks like he might burst into tears, Xiao softens. He lifts a hand, gently wipes away any stray tears that may come from Haruka's eyes. ]

I am glad you're here, too.

[ Xiao's hand moves to rest on Haruka's cheek, gently caresses it. He's handling his partner with utmost care. ]

I will do everything I can to live, Haruka. I promise you that.

[ ... ]

I don't want to be without you. Even if there will come a time where I must be...that time isn't now. I want to be by your side, not just when things are going well -- I want to be there for everything.

[ He hates that he can't be there for every big moment of Haruka's life, that he will have to prioritize his duties over everything and everyone else, but he hopes that there will be a way in which they can see each other again. The thought of that time never coming, though, is what compels him to continue. ]

You have given me so much, Haruka. I don't know if I'll ever be able to repay you, for everything you've done for me. ... I just hope that loving you will suffice.
