Transmigrated as the Side Top used as an Emotional T*sh Can

I transmigrated into a BL novel. There was only one problem. My role was the secondary top who would spend his entire life alone, harboring an unrequited love for the main bottom. You have died. Would you like to restart? The system forces me to love him and gives me penalties whenever my Affection Level drops. As if that weren’t enough, it even presents me with games that require me to risk my life. Countless repeated deaths and resets. I struggled desperately to raise the Affection Level and stay alive. If I could become the perfect side top, I was willing to abandon ‘myself.’ Hope remained impossibly distant. And as time passed, the people around me slowly began to change. The protagonists who are supposed to love each other say they love me. Even the supporting characters beg me for my love. ……How did things end up like this?
