Hiroshi Tachi) and his teenage daughter Koume (Yui Aragaki). One day, the two ride a train together after visiting Kyoichiro's mother-in-law. He sees it as a chance to get to know his daughter better, but he ends up getting more than that - by some mysterious force, both Kyoichiro and Koume end up with their mind in the other's body!

I found that this drama is hilarious yet touching. 4 out of 5 stars from me. This drama teaches how a father should understand the daughter (especially a teenager), and how a daughter should respect and appreciate a father. A good view for a lost father-daughter relationship, meanwhile it's a great refreshing for us (^__^)
