Who are you..?

I'm sure I've never seen you before...so go back.

In 1996, siblings Do Kyung-soo and Do Kyung-joo were taken to the emergency room when they were four years old.

They had deep wounds on their heads.

It was my stepfather and stepmother who did that.

Fortunately, they completed the surgery successfully.

Gyeongsu, who quickly regained consciousness, screamed and cried in shock.

Aaak! I'm scared... I'm tired... sob... Kyung... I'm so sad... sob..

Kyungsoo sneaked out of the hospital.

도경수

Ah..ugh.! My head..ha..(thud)

Kyungsoo collapsed.

도경수

Uh..um..what..where am I.!?

Kyungsoo loses all his memories...

착한 여인

착한 여인

I see... Kyungsoo, do you want to live at my house?

도경수

Yes? Is that okay?

착한 여인

Well... of course. Let's eat first. Then let's go to the hospital and get some treatment.
