My Affection Level Won't Budge [Crossover]

I'll feed my friend fic ideas: they start a story, and I write a chapter. Non-VIP stories don't count.

Here's the blurb:

Su Su transmigrates and is forced to bind herself to a dating System.

The System tells Su Su that if she successfully wins over any one character, she can return to her original world and get more money than she could ever spend.

Why wouldn't she agree to a deal that good? Winning over a man or two should be a piece of cake!

Su Su boldly enters the world, only to see who she's supposed to win over:

Target one: Nagisa Kaworu.

Target two: Reinhard van Astrea.

Target three: Berserker Arjuna.

Target four: Izuru Kamukura.

You damn System, you're obviously making this impossible for me, Fat Su!!!

System: Go ahead and make your move. If you manage to win over even one, I'll lose.

Reader advisory:

1. Everyone knows Kaworu is a national-level homo, so this can't be a purely otome story. However, all BL discussion other than Kaworu x Shinji is still prohibited.

2. No writing advice, please.

3. The author's temper is genuinely terrible.

Theme: There really isn't one
