Tokyo Love Story was broadcast during 1991-Jan-07 to 1991-Mar-18 in Japan and it was only shown in Singapore around 1994 (can't remember very clearly).
This is the synopsis of the drama from DramaWiki:
When Kanchi (Oda Yuji) first came to Tokyo to work, he is full of uncertainties. He is 'lost' in his work and his love relationship is in a mess. During those times, Rika (Suzuki Honami), his colleague, always encourages and helps him. Though they fall for each other once, all this comes quick and ends fast. Rika is simply too 'energetic' and her love is simply too 'heavy' for Kanchi.
I not only love the drama, I also like its entire sound track.
It reminds me of my youth days.
