Sweet or Heart-warming Movies

beauty inside 

ore monogatari - its cute and funny romance with a somehow  unique male lead

tokyo girl - a boy and a girl from different era connected through a phone call

bittersweet - girl fall in love with gay dude

do you mind something heartwarming, cute but with a rather sad ending

let me eat your pancreas, be with you (jp and kr ver)

This Is Not What I Expected (Chinese movie) - feel good romcom with pretty cinematography and plenty of tasty looking food (I recommend to watch on a full stomach or eat while watching lmao)

Twenty (Korean movie) - comedy / bromance with some romance (some crude humour and sexual jokes as a warning, if you don't like that kind of thing) 

The Beauty Inside (Korean movie) - supernatural-ish(?) romance, currently has a K-drama adaptation out 

Also wanna recommend som heartwarming movies:

• 3 idiots - Aamir Khan movie (india) rhat starts off soo comedic with all the bollywood dancing but it is really about a movie that shows what is learning and education and what people should strive for to succeed. A Must watch
• PK - another Amir Khan movie about religion and what and higher power
• Every childs special - a very heart wrenching Aamir Khan movie about growing up misunderstood because of dyslexia and being told one is stupid and finding put ones true talent, yet with a heart warming end.
•  Also another Aamhir khan movie titled Dangal
• Along with the Gods (both part 1 and part 2) - the hit korean movie about what it is about a fireman who needs to go through the afterlife trials to determine if he lived his life in fruitful and good according to buddha teaching
• Salut D'Amour - kinda like The Notebook with korean vibe
• Teacher's Diary - not all out heartwarming but I think its one of the most underrated and refreshung thai drama
• Hula girls - about girls learn how to hula to revive the towns that had a mining industry that is dying
