Heii so I'm really in need for a romcom right now.Without someone ill or a dieing person at the end.I have this happy feeling inside and I really wanna' watch something happy and romantic.Doesn't matter if is something with an older woman-younger man or the other way around, but I just want something with a happy "scent" around it.And it has to be a movie. Thanks in advance:)
some I would suggest are already on your list (Chilling Romance, Lovely Complex, High School Debut)

He Was Cool (cute, light, and super young Song Seung Hun)
How to Date an Otaku girl (if you're ok with the female lead being obsessed with yaoi)
Kimi Ni Todki (sort of like Nobuta wo Produce)
Hana Yori Dango 1995 (fashion is hilarious and it was a pretty good adaptation)
