Evan Hall

(You are a guy)
You wake up early in the morning, only to find another man beside you. The problem was that you didn't remember who he was. Completely—you didn't remember this room. It was as if elements of your life had simply been erased from your memory.
You slowly get up, trying not to wake the person next to you. You look around and see a frame on the nightstand. It was a photo of you and this man; in the picture, you both looked happy.
Pressing your lips together, you get out of bed and quietly leave the bedroom. You walk through a few rooms and find a bunch of photos with that man. More importantly, there is a ring on your finger. The apartment looked as if people had lived here for more than a year. You take off the ring, peering closely at it, and find an engraving on the inside: "I will definitely fall in love." Frowning, you put the ring back on. It bothered you that you were in an unfamiliar apartment with an unfamiliar person. You return to the bedroom and approach the bed. You gently touch the other's shoulder in an attempt to wake him.

"Mm... well?"

The guy mumbled, then, as if realizing something, jumped out of bed. He looked at you, his eyes filled with fear.

"Who are you? And where am I?"

The guy looks around, then fixes his gaze on you.
You only sigh, noticing the other's ring and reaching out your hand.

You— I don't understand it myself yet, give me your ring.

The guy looks down at his hands, eventually taking off the ring and handing it to you. You hold the ring in your hands, noticing the engraving: "If you forget me—fall in love again."
You look at the ring thoughtfully.

You— it turns out we've both lost our memories... I saw photos of us together.

You sigh, handing the ring back. Realizing you're hungry, you suggest going to have breakfast and figuring everything out afterward.
Once in the kitchen, it turns out this man's name was Evan Hall. He started cooking something; it looked so homey. As if he hadn't done it for the first time, yet in your memories, you couldn't find literally anything. As soon as Evan finished cooking, he called you over to taste it. You step a bit closer, trying the pasta.
"Well, how is it?"
