If You Are All Reincarnated as a Gal, Who Is Still the Moon Elder?

My name is Takeru Sato, an ordinary basketball club member whose specialty is a bitchy mouth. When I woke up one day, I found that I had traveled back in time to a galgame I had played - not the protagonist, but the good friend next to the protagonist who appeared for three sentences in each chapter and whose role was only to make pornographic remarks and get beaten. What's even more outrageous is that the system told me: If the "protagonist" Tanaka Yuta of this world can successfully fall in love, I can go home. I laughed. The task is simple. Because all five heroines like him, and every one of them is pursuing him. Then I realized I was wrong. Big mistake. ——That bastard actually refused them all. The reasons were: "She just relied on me", "She just thanked me", "She was just used to working together", "She just took the initiative too much", "She just confused gratitude and love". Me: "??? Do you have any misunderstanding about 'love'??" Tanaka Yuta (serious face): "There is no misunderstanding. I just don't deserve to be liked." ... It's over. The protagonist is hopeless.
