Dososei(2014)

Dososei is a Japanese drama series that reunites old flames at an alumni gathering. Kenta, a divorced man now running his family's laundry business, reconnects with Akehi, his junior high sweetheart who is trapped in an unhappy marriage. Their rekindled attraction complicates both their lives. Elsewhere, Kaoruko, a brilliant but guarded woman scarred by past romance, crosses paths with Ryosuke, a serial womanizer incapable of commitment. As these four lives intersect, each must navigate the tension between nostalgia and reality, between what they once wanted and what their current circumstances allow. The series explores how second chances rarely come without cost, and how the people we were aren't always the people we've become.
