I'm not sure what you're confused about but he was doing everything for himself. He wanted to control her because he couldn't control his feelings for her. He kept on justifying he was treating her as his sister but still had romantic feelings for Penelope.
He was gifting her items to hopefully see whatever little affection she used to show be given. Remember in earlier chapters their relationship wasn't too bad. But his obsession and self-hatred due to his affections for her was kind of a self-fulfilling prophecy. It practically scared her off coz she could never do anything right in Derrick's eyes. He loved her but hated her too for making him feel certain ways.
He really is irredeemable just for the simple fact he wanted to control and cage her but hated and loved her. His conflicting feelings made it so easy for the fake daughter to brainwash him.
Did that make sense?
Too late did I realize how often I repeated his feelings. Haha sorry about that
WHATT HIS FEELINGS WERE ROMANTIC IN NATURE???? i thought his conflict was bc he couldnt accept her as his sister bc he didnt want to replace her as yvonne but now that hes starting to love her as one thats when he was feeling conflicted
Okay that’s what I thought cause some of these comments were very contradicting and I thought I was missing something. Thanks for explaining (●'◡'●)ﾉ
Can someone who’s not biased explain ch 178 interaction with Derrick and Pen. Like the fact where she says she understands why he was gifting her and doing all this stuff suddenly to her.
