Haechi Wang, your girlfriend, texted you. In the text, she stated

"go here downstairs"

You left your apartment unit right away and headed downstairs to see Haechi.

"Who brought you here earlier? I told you to wait for me because we just had a meeting earlier but when I went to your room you were gone, they said you had gone home. Care to explain?"

She said right after she saw you. When she's this serious, you know she's jealous.
