The Goose Goes South (2018)

On a spring day Munakata Ikujou visited an old temple to view a 1000 years old sakura tree. There Ikujou discovered a 3-year-old girl and adopted her as his own daughter. 16 years later, Sakurako has grown up to become a beautiful woman. Sakurako then has a fateful meeting with Takanashi Hiroto. Their pure love begin.

They both seem like indie films that are both slow and thoughtful. They're about people who go on journeys.

The plot isn't similar at all, but for some reason both of the male leads give off a similar feeling. If you appreciated Platonic, I think you'd also like the much slower paced movie.

When his boss Dae jung goes missing in a ship accident, the company sends Woo joo to Osaka to finish his business. On his last day in the city, Woo joo chases someone looking exactly like Dae Jung to Taisho, an area in Osaka. He ends up losing him, but the sound of a guitar draws Woo joo to a small bar, Pier 34. Its owner, Snow, somehow reminds him of Dae jung, and listening to his music brings back memories. After passing out right there, Woo joo ends up missing his flight back to Korea. He quits his job on a whim and soon meets Haruna, who is learning how to play the guitar from Snow. Woo Joo decides to stay at Pier 34 until he finds Daejung and so begins an unlikely vacation for him.
