Rabukome Manga ni Haitte Shimatta no de, Oshi no Make Heroine wo Zenryoku de Shiawase ni suru

Trapped in the universe of a beloved romantic comedy manga, my sole purpose as the protagonist’s best friend is to ensure the rejected heroine, Sei-chan, finds true happiness. “I promise to bring joy into your life. Will you be mine?” This unexpected turn of events places me in a unique position—determined to rewrite her story with a happy ending she truly deserves. Though originally just a side character, I’ve taken it upon myself to change the narrative’s course. Every moment spent with her strengthens my resolve to erase the sadness from her eyes. The original plot may have destined her for heartbreak, but I refuse to let that stand. Through small gestures and heartfelt words, I’ll prove she’s worthy of love. This journey won’t be easy, facing both the story’s predetermined path and her own doubts. Yet seeing her smile makes every challenge worthwhile. In this manga world where everyone roots for the main couple, I’ll be the one cheering exclusively for her happiness. The pages may try to dictate her fate, but I’m ready to defy them all for her sake.
