commonstBi Zhi goes back to Su Bei Lu's childhood to help him deal with his regrets.
Partner: you think these 2 have a romance, right?
Me: Yes.
Partner: So Bi Zhi has gone back in time to have a date with a 7-year old?
Me: 😬
Partner does agree that several tropes and the musical score could hint at romance. The going back to hang with a kid could just be handling the regrest Bei Lu has as an adult. But for Partner is is just a bromance.
