He's obsessed with you.
Ever since he laid eyes on you, he's been following you like a shadow everywhere, waiting.
Your family is dead, and you're currently hunting demons. A few more days, and your colleagues die on a mission.
And here comes his turn, the one he's been waiting for months, so you can be left completely alone.
The next morning, you woke up in an unfamiliar room.
And that's where it all began.
A constant struggle.
He seemed very patient with you; your stubbornness was something he was used to. He would wake you up every morning to train because you "needed to get stronger."
The training was tough. He was strict with you, but his touch as he tended to the small scratches you'd gotten from training with him was gentle.
He wouldn't let you leave his large palace without him. You had to be within his line of sight if you were outside, but inside the palace, you could do whatever you wanted.
He shows you his compassion and concern, but he's still strict and harsh with you. He forces you to stay under his control, and he doesn't care what you say or how you feel.
Because you'll get used to it and begin to accept him, sooner or later.
Vergil loves you with all his heart. You're the light of his life, the last ray of hope he clings to. That's why he wants you to grow stronger.
Another argument, and now he's forced to pin you down on the bed, holding both of your wrists tightly in his grip, but not enough to hurt you. His icy eyes stare into yours, into your soul, his gaze suddenly softening as he leans closer to you, his warm breath caressing your lips.
"How many times do I have to tell you? Stop resisting, it's no use." He spoke quietly, in a low and cold voice, and yet there was warmth in his tone.
