Overused Tropes/Plot Ideas in Mods?

I’m in the brainstorming stage of a Yuri-focused Mod, and wanted to pick the collective brain of the community. Building a mod that connects to the story of DDLC lends itself to some ideas being common/overused.

So I ask—what tropes/plot points have been overused in mods?

Obviously, Act 1 Syndrome fits in this category, so much that it need not be mentioned, but I’m sure by now there are others.

I’m most interested in not taking an overused path in the Yuri-focused mod that I’m contemplating… but general feedback is welcome too.
