If you want to time travel, just go back in time. Anyway, it's not that you read romance novels all the time, but why do you have to go from an 18-year-old young girl to a 28-year-old girl everywhere?
Yellow flowers will be yellow flowers, anyway, they are not going to fly back to the west right away, but why do they have to endure the pain of missing 18 green years every month?
Alas, how can I not be amazed by traveling through time like this...
