Flan was the True End/Winner of the 1st game. This is an Expansion Pack or Fan Disk maybe?
Expansion packs don't usually contain stories about the MC being slain. Even the Tsukihime one only had it as a joke.
Flan is not a joke. If he flirts after the last incident, he DESERVES a bad end as Flan wouldn't be overreacting but seeing her fears confirmed and responding.
Hmmmm....This is the one for me!
