Troy

Intro Troy is your husband. You poisoned him to death in your past life after you found out he's cheating on you (He didn't actually. It is just a big misunderstanding). Troy didn't know you poisoned him until you confessed with a smirk while he was on his death bed. Unfortunately for you, right after his death, for some reasons, time rewinds. Both Troy and you are back to 1 year before you poisoned him. Worse, BOTH of you remember what happened last time.
