This is the S rank/proposal script for the gay male character. SPOILERS
Script
ZERO: Master Kamui.
KAMUI: Good day, Zero.
ZERO: It's a bit sudden, but hear me out. I'd like to discuss some rather adult matters with you.
KAMUI: Adult matters...? Uh... I see.
ZERO: I suppose that the adult matters I normally bring up tend to be real shocking. However, the matters today are of a different nature.
KAMUI: Gotcha. So, what's up?
ZERO: Master Kamui, what do you think of men who have pasts they refuse to speak of?
KAMUI: You mean yourself, Zero?
ZERO: Yeah, that's right.
KAMUI: What's gotten into you? Why would you bring that up so suddenly...?
ZERO: Would you be able to build a future with a man who refuses to speak of his past?
KAMUI: Build... a future...?
ZERO: What I mean is... would you marry me.
KAMUI: M-Marry you!?
ZERO: Yeah. I have a past that I cannot speak of. The only person to accept that, and trust in me in spite of that.. is you, Master Kamui.
KAMUI: B-But uh, I'm a guy, you know?
ZERO: I know that. I know that you're a guy, and I know that you rank far above me. I.... I like you, Master Kamui. No matter what anyone might say, I can't keep that to myself anymore.
KAMUI: You... You really mean it, don't you?
ZERO: Yeah, I've never felt this way before. It's nothing like the loyalty I feel towards Master Leon. There's this heat inside, that won't leave me. It's strange. I love the look on others' faces when they suffer, but when your face grows dark, Master Kamui... something inside my chest starts hurting... I want to protect you with my own hands, to treasure you, and totally spoil you. And... if possible, I wanna make you happier than anyone else in the world.
KAMUI: Zero...
ZERO: Master Kamui... will you marry me?
I guess not... hearing a man say the kinda stuff you'd wanna hear from a woman...
KAMUI: Even if you can't speak of your past...
ZERO: Huh?
KAMUI: We can speak about the future together, can't we? Could you talk with me about everything from your past to your future? In that case, I... shall accept your proposal.
ZERO: Master Kamui... are you sure? Really? You're not gonna regret this... are you?
KAMUI: I won't regret it. I'll admit... I'd be lying if I said I'm not surprised, but hearing your words... made me so happy. I want to accept your feelings. I want to find happiness together with you... I want to be with you from now on, and for all time.
ZERO: Thanks... I knew I had my eyes on the right guy.
KAMUI ... Haha. It's an honor, Zero.
