ML dies

If you ship the main couple it's a sad ending as they separate. If you don't (like me), it's a mostly happy ending.

FL dies

no one dies but it's an absolute tragedy anyway

the leads separate after the FL returns to her real body and the ML, believing her dead, fails to recognize her upon meeting her again
