Seeing him coming to her rescue when she was fake dying was just too hilarious like when a kid is throwing a tantrum and the parents pretends to leave he's totally the same. Like a puppy lol
The heroine is a dummy. She completely disregarded the story believing it'll still end up the same way as the novel plot even with her change of personality. She got cocky, huh.
I'm annoyed too but that's only because I can see Del's point of view. I know that he genuinely cares for her (somewhat) but to her, he probably looks like a lion playing with a mouse. lol
"for a long time."
lol probably till his death.
