If I changed her to look like me, she would be taken care of for the rest of her life.

"Hmm..."

I was groaning alone in a small general store.

Today is my girlfriend Yurina's birthday.

I had completely forgotten about that and came in a hurry to look for her birthday present.

"I guess I have to go to the department store in front of the station..."

Just as I was about to leave the store while muttering these words, a certain product caught my eye.

It was a pair of rings.

"Um, give me this!"

After a moment of silence, an old woman came from the back of the dimly lit store.

"Oh, you want that ring?"

"Yes. I was thinking of giving it to her as a birthday present."

"That's a problem. I thought I'd gotten rid of it a long time ago..."

"Eh, is this a defective product?"

"Well, that's about it. This guy has some magical powers."

"M-Magic!?"

"That's right. If you put this ring on your finger and imagine your ideal partner, the person who wears the other ring will transform into that image."

"Oh, really? That's amazing!"

"But there's one problem. Once you're transformed by the power of the ring, you have to stay that way for the rest of your life."

"Isn't that great! It means we can both stay youthful, right?"

"I see. Do you have that kind of thinking? Well, if you're the owner, I don't think there's any problem with selling it."

I paid for the ring and received it.

"Listen, you only have the power of magic once. Use it carefully. If you make someone gain weight just because you like chubby people, no matter how hard you diet, they won't be able to lose weight. If you turn someone into a young child just because they're a lolicon, they won't grow up and will remain a child for the rest of their lives.''

"I know."

I hurried out of the store, only partially listening to what the grandmother was saying.

"happy birthday!"

When I arrived at Yurina's apartment, I congratulated Yurina as she peeked out of her door.

"You're late. I thought you forgot that today is your birthday."

"Haha, no way..."

I can't believe I forgot about it just a while ago.

``I went to buy a cake, but I wasn't sure which one to buy.''

I offered her the cake I had bought in a hurry on the way there.

"Wow, that looks delicious! Come up, come up. I'll prepare some tea now."

After Yurina and I finished eating the cake, I took out the ring from my bag.

"Yes, this is it. Birthday present."

"Wow, thank you! Is this an engagement ring?"

"Ah, no, that's not what I mean..."

"What? That's fine. Thank you."

Yurina took one of her rings and immediately put it on her finger.

"Actually, I have another present for you."

"Oh, really? What?"

"Hehehe. I'll give you the gift of an extraordinarily wonderful body."

"Eh, what is that? Did you make an appointment for me at the beauty salon?"

"Well, I guess it's something similar. Wait a minute."
