Oh boy. I'm kinda feeling sorry for that senior now, I mean WHO LEAVES THEIR PHONE UNLUCKED AND IN THE PRESENCE OF A GIRL????? That guy is so screwed now. My bet for next chapter is: Soo Ah checks his phone (obviously) goes to the look a like folder checks it, delete the photos, checks other folders and does the same and finally leaves the place leaving the now empty phone in the table for the senior to find it alone without Soo ah there.
