I cringed at the team building arc. Saeon is so smitten and it's cute, but I kept getting second-hand embarrassment, and I'm worried others will think Heejoo is a homewrecker.
I died when he gripped her hips, lifted and sat her on the table, and tried to hike her skirt up. That scene makes up for the brain cells I lost from Heejoo's impulsiveness and Saeon's inability to notice something different about the caller's speech.
