10 dramas/movies with ____? #4

Yes, anything is fine that has to do with trying to draw attention to something for sale or to get people to sign up.

6. Fly, Again - Idk if it counts.. ML wears the bunny outfit to handout invitations, but FL steals the head part, and he chases her, so he doesnt actually stand there and handout the  invitations.

9. Please Love the Useless Me (does this count? not an animal costume, but a plant flower. If this doesn't count you can count it as a bonus and not count in the 10)

10 Dramas/Movies which one of main characters, ML or FL lied or has a secret about his/her real age.

Does it have to be a long running lie, or can it be for a brief period?

3. Liar x Liar

4. Sumika Sumire - not sure if it counts. FL is 60 but transforms into a 20 year old. She hides the fact that she is actually a 60 year old woman.

If number 4 counts

6. 55:15 Never Too Late - they are all 55 year olds who are transformed into their 15 year old selves and they try to hide that from some people

Hi Raining Sunshine,  to allow others a chance to put forward their possible answers to the topic, there is a limit of three titles/shows per person.

That said, I've been trying to think of an answer to the current topic so appreciate your answers as I've seen some of them.
