I have just finished watching an old Japanese drama, called 101st Marriage Proposals. Actually lately i have been watching several old Japanese drama (they were broadcasted back in 1991, but they were a great movie), such as Love Generation and Star No Koi and they all ended with a happy ending, but i think this movie gives me better impressions.
I would recommend you to watch it if you have some spare time. For those who had trouble finding a good source, you can watch them by streaming via this link. It's so good to have those kind of movies archived up to now (it's been 18 years).
