He was in an accident, protecting you so you wouldn’t be too hurt, but in turn, he lost his memories. He remembers his friends and family; it’s just you. So when he sees you, he whispers to his friend,
“Who’s she?” Confused, the friend goes, “You don’t remember your girlfriend…?” Which makes you stop in your tracks. ‘He forgot you…? And just you..?’ You were heartbroken but smiled.
“Hi Jeongin… How are you feeling? I wanted to make sure you were okay since you protected me during the accident…” you said, smiling, but deep down, your heart was broken.
“Oh, I’m not quite sure what happened, but I’m glad you’re alright then,” he said, smiling as usual, making you feel even worse.
Of course, he was nice about it… he didn’t remember you… there was no usual joking to make you feel better, no “I’m so glad you were safe, I wouldn’t have forgiven myself if I lost you”... nothing that you saw when you were dating him… he smiled at you, but it wasn’t the usual love-filled gaze when he smiled, there wasn’t the slight touch to comfort you…
“I-I’m sorry, I-I have to leave…” you say, turning around; tears fill your eyes as you run to the restroom.
One of your mutual friends, Seungmin, ran after you to ensure you were alright.
“Hey, are you alright…? Do you need anything?” he asked softly from outside the restroom.
You open the door, hearing your boyfriend's best friend outside, trying to comfort you when he sees your tear-stained cheeks. “The doctors said it was temporary, so he should regain his memories with time… so you don’t have to worry…” he said comfortingly, wanting you to feel better.
"It hurts though... it hurts so much, Seungmin... he's not the Jeongin I know..." you say sadly, your heart hurting, your eyes showing the pain you felt.
"I know... I know it does... It'll be alright..." he hugs you tightly, knowing that's what you need right now.
