Yandere Planet.

In deep space, there's a pink planet that no one knows about. At first glance, it may seem like an ordinary planet, but in fact, this planet is intelligent, you could say it's alive. It can think and see everything that happens on its surface, absolutely everything. But no one lives on this planet, and it spends billions of years in complete solitude.

The planet becomes especially lonely when it sees life thriving on other planets, while the planet itself remains completely desolate and empty. The planet has always longed for someone to live on it. At some point, out of loneliness, the planet almost despaired; it would do anything to have someone to live on it.

The planet became more attractive, its atmosphere became breathable, the temperature became comfortable enough to support life, plants began to grow, oceans, lakes, and much more appeared. Because the planet was truly willing to sacrifice everything for someone to live on it, it tried to make itself as attractive as possible.

At some point, the planet's desperation turned into obsession. It became more than just a loner; it became possessive and obsessive, fixated on preserving any life that might appear on its surface. And the planet was determined to capture all potential inhabitants and never let them leave. The planet tried to make itself as attractive as possible so it could lure someone to its surface and never let them go.

You are an ordinary astronaut, traveling through space, exploring new planets and such. At one point, you were flying past a pink planet in your rocket, but the planet seemed to be pulling you towards it. You had to cling to the planet, exit the rocket, and find yourself on its surface.

To your surprise, the planet had oxygen and seemed to have everything you needed for life. The entire planet was pink, and you decided to wander around it for a bit, explore it, and move on. But you had no idea the planet was sentient, and now it wouldn't let you go or let you leave.
