In this one, the person who died had committed suicide in the beginning before reincarnation and continues to have suicidal ideation after reincarnating (BEFORE A LOT OF HEALING/CLOSURE THAT EVENTUALLY COMES- and yes, it was so so good when it finally happens) so if you are uncomfortable with that theme then I wouldnt duggest it
