Stella was kissing her boyfriend in the garden while 7-year-old Helena and 10-year-old Diego were spying on their sister from a bedroom on the second floor.

Both children had binoculars to see what was happening and they made a plan to interrupt and disturb the young couple.

Yongsun had been improving her cooking skills lately, and she decided to look for her two primary assistants. The ones who liked to taste everything.

The black-haired woman got into the room without making noise because the kids had forgotten the door right open.

The mother thought they were just cosplaying any spy movie or series and walked slowly, ready to scare them in a playful way.

Diego and Helena exchanged a second look and the ten-year-old boy lifted his hand:

__ Can I speak, Mom?

__ Go ahead.__ The woman kept a serious face.

The boy said, and he meant it:

__ I had the idea. I’m sorry, mom.

__ Is it true, Helena? Did your brother came up with this plan to watch Stella and her boyfriend?__ Byul-yi leaned closer to her daughter and looked into her eyes.

The cute girl blinked non-stop and finally confessed:

__ Naaaah... Dieguito is protecting me, Mom. It was my idea.

The woman turned around and took a deep breath.
