Actor Keisuke Koide and actress Saeko are currently dating. They hit it off while working on the drama "Oishii Proposal," which aired this spring. The couple is somewhat unusual because they attend rival universities Waseda and Keio. Koide is a fourth-year student at Keio, while Saeko just entered Waseda in the spring. The two will again appear together this fall in the Nodame Cantabile drama series.
