Open an umbrella and wait for it to fly.
Looks like black and white and odorless life, in fact, our hearts
Have a beautiful sky of their own.
☂ The place where the black umbrella is,
About 32 degrees, the ink will become transparent.
At this time you can see the secret hidden under the umbrella!
❶ You can find friends/ family/ lover to interact
There are better objects, please find her / him out
If you are lonely without a friend, you need this postcard more!!
Please immediately go out and hold the first person who passed you in front of you ((Please be asked not to find me ~ escape ~ ~))
借 Use your hands to help the other person's hands rub the heat
(Winter helps her/his hands warmly.)
请 Place the palm of your hand on a black umbrella after rubbing heat.
❹ Wait a few seconds...
❺ Take a look at the surprises under the umbrella
