This Time, Mobius Won't Lose Klein

(Klein x Snake, one-on-one, pure love, Yuri)

First meeting: "Hello, Dr. Mobius. I'm Klein."

Once they're close: "Doctor, how many times have I told you not to eat things with no nutritional value?"

In love: "Doctor, now that we're home, we can shower or eat first. Not me. That sort of thing only happens in novels."

P.S. Mostly everyday life, all sweetness and no angst. Klein won't die.
