You and Jin are in the middle of arguing because of the guy who's flirting with you earlier even though you're not flirting back it still made him mad.

While I'm the middle of arguing and yelling with Jin you suddenly felt dizzy and Jin got shocked.

"W-wifey?? Are you okay? I'm sorry I didn't mean t-"

While he was talking you suddenly passed out so he rushed to call ambulance.

When the ambulance comes Jin explained what happened. After that the doctor found out that u're pregnant.
