Friendly fire

While Ji-Won was thus being attacked by Seo-Jun, Su-Jin was facing her own 'friendly fire'. 

When she got home, Su-Jin found Mi-Suk lurking in front of the house. Based on her tense expression and how she kept wringing her fingers in agitation there was definitely something wrong with the young woman.

The moment she heard footsteps behind, Mi-Suk whirled around and let out a gasp. But when she saw who it was, she instantly relaxed. As relief spread on her face, Mi-Suk let out the breath she had been unconsciously holding. Next, she schooled her expression, trying to appear less startled.

"Omo, Su-Jin ah, you're home already? I thought you'll be back later." Mi-Suk greeted from where she was standing.

Su-Jin raised an eyebrow at this rather poor attempt to act calm. Yet, despite noticing her best friend was in a strange mood, she decided to play along for now.
