Aku gatau ini termasuk sad ending atau ga but i recommend you to watch monster, 2037, hello ghost, pawn, grave of the fireflies, and children of heaven.
Honestly I rarely watch films with endings like that, tapi pernah dapat rekomendasi dari orang lain judulnya Be With You, The Notebook cuma gak tau ini sesuai sama yang kamu cari apa gak.
la la land, a walk to remember, midnight sun, me before you, on your wedding day, titanic, the fault in our star, paper towns, remember me, tenggelamnya kapal van der wijck, dear john
