Please help me pick out a Too Cool for School item for under-eye bags ㅠㅠㅠ Please!

I've become interested in under-eye makeup lately, so I've been looking it up.

I heard the Too Cool Protoge Pencil is famous.

I looked it up and saw that #1 and #9 are the most famous... ㅠ

It's sold out every time I check.

It was buy one get one free on Kakao Gift... but I don't want to buy two of the same thing...

Should I wait for #9 to be restocked, or buy a different color...? Rosy Dew seems pretty nice too...

If anyone has used this, please recommend a shade for the under-eye area. Or you can recommend a different product too.
