Love You to the Stars and Back (2017)

Love You To The Stars and Back is a film that takes on a mature vibe. Compared to Vince & Kath & James that is fluffy and quite the romantic, Love You To The Stars and Back talks about two youngsters and them questioning life and whatnot. From the get go, it doesn't sound like they have any similarities.
It may not have the same premise and story, but it does star Joshua Garcia and Julia Barretto.
If you're willing to see more from those two after VKJ, then I highly suggest this movie :)

Both films show two strangers whose awkward initial encounters bloom into a curative kind of love, with different stories representing the emotional struggle most young adults and grown-ups undergo, 'Love You to the Stars and Back' and 'That Thing Called Tadhana' exhibits that love does cure all.

similar cancer storyline where both the ML had cancer. Both a re tear-jackers too and will have you weeping at some point. However, the filipino movie has a happy ending but the japanese one is a tragic one sadly.
