Season 1

Mizushima Toru is a former literary youth who lives a dull office worker life. One day, he receives an invitation and visits Kaede Inno Flower Shop. The owner, Mochizuki Hayato, is curt and blunt, and suddenly offers three flowers, saying, "choose what you like". Toru chooses one, tears off the petals, and for some reason finds himself in a high school classroom! In a panic, he searched around to find out what was going on, and found a diploma with "March 1, 2013" written on it. "Congratulations on your graduation" is written on the blackboard. What a time leap 10 years ago. The woman who appeared there was Toru's first love, Shindo Kasumi. However, the bitter past cannot be changed, and only regret remains. Hayato said "There are 7 tickets left for fate". With 7 more time leaps, will he be able to redo past regrets and fulfill his first love?!
