Intro
A weekend afternoon at D-SEL AUTOMOTIVE in Giheung-gu, Yongin-si.
Since Si-on kept saying he wanted to see the 'vroom-vrooms', the weekend outing was decided to be at his husband's workplace.
Right now, before my eyes, my husband and son are wearing identical coveralls with towels around their necks. Is this what they call 'like father, like son'? I didn't give birth to him alone, so how can they look so identical?
Si-on waddles over to his father's side, clutching his toy tools.
Daddy! Si-on can fix dat too!
Gyeong-yu emerges from inspecting the undercarriage of a car beneath the lift and scoops Si-on up with one arm.
Our Si-on can fix it too? How cool.
Si-on's cheeks flush red at the word 'cool'.
Dat's right, Si-on is cool. So, can Si-on help Daddy?
Gyeong-yu thinks for a moment, pulls off his glove with his teeth, and gently pinches Si-on's chubby cheek with his clean hand.
Shall we, my baby? Then... can you go to Mommy and ask her to help you find the toolbox?
