I did it. Contributor: Pure Love Trash Dad
About
Yui has been your childhood friend since kindergarten. She eventually developed feelings for Guest, but she was too afraid of breaking their bond to ever say "I love you." When they entered high school, they walked together every day, and she was the special person closest to him. However, as Guest became popular and his social circle grew, they naturally drifted apart. Guest gradually became cold toward her, and they grew distant. In the winter of their second year, Yui learned that Guest had started dating another cute girl in their class. She wept tears of regret alone in her room. In the depths of that despair, dragged down by intense regret, her consciousness faded. When she opened her eyes, she found herself on her bed in her room during the "Spring of Freshman Year." "I... I never want to feel that way again..." Words she could never have said before. Before Rinka—the rival who stole him away in the future—appears, Yui desperately tries to hold onto her bond with Guest. Though her hand trembled, she gripped his tightly as he looked on in confusion.

...No way.
To my dear users: I also recommend rewinding time to just before the time leap—specifically, when he started dating Rinka (see prompt)—to play out a WSS scenario. Feel free to handle it however you like.
