Only serious about you - Kai Asou

Yoshioka is a regular at Oosawa's restaurant, and always seems to be bringing in yet another boyfriend to enjoy Oosawa's delicious cooking. As a single parent, Oosawa works very hard and doesn't have time to make many close friends, or even consider dating. But when his beloved daughter Mizu falls ill and Yoshioka offers his help, Oosawa finds he must accept this frivolous seeming person's outstretched hand. Yet, sometimes people are not quite what they seem, as Oosawa discovers. A tender romance story of a single father, a lonely businessman, and the child who brings them together.
