Well...

Lunalel is getting into a threesome.
Sven is in class.
Neko is harping on Gwynn
Lyssa is running towards some sweets.
Etc.

So I'm going to take my options and have Lukas hit on Lyssa and then cause the plausible mistake of Gwynn thinking Lukas is Sven obviously.

Sounds like the best course of shenanigans and a one way ticket to hell for Lukas... metaphorically and physically.
