An - romantic yandere DG :))
****
Girl run.
That's literally the only piece of advice I could give if we're talking about DG as a romantic yandere.
The worst of it isn't that he's obsessed and borderline crazy. No. The worst part is that you won't even really notice it until it's too late to leave.
He starts off so sweet, the picture of a perfect gentleman.
Flowers, gifts, romantic dates, lovely sugarcoated words - lies, sweet smiles and passionate kisses and embraces.
He truly is the perfect other half you've been looking for - or so you thought.
There are two versions of events: how you met him, and how he met you. Really, you shouldn't be so comfortable and sure of who you let into your life. You never know who someone really is until it's too late.

You met DG while you were out with friends.
Before he became a famous idol, a short while before his debut, he was parading about with his fellow trainees in a hidden little restaurant, tucked away in a side street far from the bustling main street a few feet away.
The group of trainees, tired and happy for their much needed day off, had taken refuge at a table pushed far into the corner of the restaurant, DG sitting in the corner, facing the entrance of the restaurant.
They'd already finished their meals by the time you'd arrived, wrapped up in a thick scarf and coat to ward off the cold.
You were accompanied by two or three friends, not that he paid them much mind.
Breathlessly, you had taken a seat at one of the tables near the front of the restaurant, unwrapping the thick scarf to reveal your face, split with a wide smile.
Your small group laughed and spoke, pausing momentarily to order before continuing.
The sudden silence leaves you confused, that is until you turn and spot possibly the most beautiful man you've ever seen standing behind you.
He would introduce himself in a calm, cool tone, telling you about how he saw you from across the room and had to take the chance to introduce himself to such a lovely lady.
Words meant to woo you - and they work. Both you and your friends find him charming. You don't question why a handsome man decided to greet you out of the blue - you were never one to look a gift horse in the mouth.
Because of that, you don't reject him when he asks to see you again.

The first date is memorable, as first dates usually are. He takes you on a picnic in one of the most beautiful nature reserves you've ever seen. Everything is covered with a light sprinkle of snow, but the two of you remain comfortably warm underneath a heated outdoor patio.
He's the perfect gentleman, doing everything exactly right. It almost seems like he's able to read your mind, everything going exactly as you'd hoped.
One date turns into two, and then another, and another after that.
Soon enough, the two of you are inseparable.
He lives on a very busy schedule but always seems to have time available for you.
Sometimes he plans to see you in advance, other times he'll show up unannounced to whisk you away for a quick lunch date or coffee run.
Regardless of how busy he is, he seems to put you first, pushing aside any and all responsibilities in favour of spending time with you. Honestly, he's a wonderful boyfriend, someone you could really see yourself staying with for a long time.
