Here is some news I found:
A Given original film was announced on September 19, 2019. It is slated for release in 2020. The production staff and voice cast of the anime adaptation will return for the film. The film will be a direct continuation of the anime series and will adapt the second arc of the manga, which focuses on the relationship between Haruki and Akihiko.
People are soulmates or fated together when things feel right being together. Not because you liked someone once upon a time and they come back into your life. Life changes and so do we. A soulmate is someone you share your life with and love everything about them. Period.
