Didn’t she remember a prior timeline previously through her relationship with him?
Perhaps that’s carried over and she’s been using that knowledge to reach the heights he helped her to prior.
She’s either putting on a front or annoyed he stopped coming for her.
Don't know about blessings or curses, but I assume that Rena has been putting her memories to good use, and is not all too pleased that the skele of her heart was prancing around without her.
Honestly it's starting to get boring because of how often he cluelessly walks into traps and is just reacting to stuff. A good MC is proactive, not reactive.
