Sigma

What should I do?

It seems that my classmates recommended a new and interesting mobile game, in their opinion.
Maybe we should try?

Quickly taking your phone out of your pants pocket, you went to the search engine, and in less than five minutes the game was downloaded.

By clicking your finger on the cute pink icon that appeared on your screen, you entered the game.

"Love Forever"—the game's title hung at the very top, in large, white, shiny letters.
Below the title were yellow buttons for "Start Game," "Settings," "Complain," and "Exit," and to the side were three characters: a short, blonde girl, a tall, brunette girl in a mask, and what appeared to be a boy with pink and white hair.

You launched the game.
At the very beginning, you were asked to enter your name, and then to choose a "new love."
There were about eight characters, but you personally liked a guy named Sigma. I think he was even on the splash screen.

You chose Sigma, and the game began.
A small pixelated apartment appeared on the screen, and in a small but bright hall sat the boy Sigma.

"I'm so glad you chose me! I hope we get along. Would you like to help me clean up?" The guy's voice was clear, yet soft and pleasant. He smiled slightly.

...

And so about a week passed.
Every day after school you went into the game to see your "boyfriend", until one day...

When you turned on the game again, you noticed that Sigma was nowhere to be found. After searching for a while, you found him in the bathroom. He was sitting against the wall, his knees pulled to his chest, sobbing softly.

"Oh, you're already here? I've missed you so much! I miss you so much. But... But... I know how to make sure we're always together, so I can finally see and hear you! You want that, right, my love...?" He frowned sharply at the last sentence, but the game's graphics made it look cute.

"Click the little white button in the upper right corner," he continued, smiling again and coming to his senses.

Strange. Very strange.

Will you press the button?
