First person. I don't know what the potential triggers are, so if you don't like it, don't force yourself to read.
After I died from working overtime, I got bound to the "Strongest Seduction System."
The System said that if I could flirt with Satoru Gojo, I could return to Earth.
Day 1: I said a cheesy pickup line: "Your eyes are more beautiful than the Six Eyes."
Day 2: I brought him strawberry daifuku: "Your smile is even sweeter."
Day 3: I kissed the corner of his mouth: "Seal of approval. You're mine now."
Day 4: Satoru Gojo pinned me against the wall: "You think that's enough to get you home?"
Day 5: He took off his blindfold: "Want to see the real Six Eyes?"
Day 6: My escape failed. He grabbed me by the back of my collar with a laugh: "You flirt and then run away?"
Day 7: A Special Grade Cursed Spirit attacked. He stood in front of me: "Don't be afraid. I'm here."
System notification: Seduction progress at 99%.
Wiping away blood, I smiled bitterly. "What's left?"
He leaned down and whispered in my ear: "You still haven't said... that you love me."
