This is the sweet story about life, love and friendship in a dormitory named Diamond Hall.

Taeyeon nervously get out from the taxi, checking everything that no bags or stuff left, She stood in front of this huge dorm building, right beside her new school. She went up the stairs carrying all his bags, which were bursting because of the large amount of "necessities" she decided to take from home.

She was so nervous she almost tripped. She had never lived away from home. Sure, She is naturally independent, but She really did not know what to expect at college. Everyone always told her college is the time when people change, or "grow up." She understood the words they were saying, but did not fully comprehend the true meaning behind them.

Taeyeon also feel so nervous since she felt like she’s the last person who checked in in this dorm. She was late for the dorm enrolment because at first she thought she’ll just easily rent a room near campus, which turned out she out of luck. Living together with someone else is really not her forte.

Taeyeon dropped her bags as she finally reached her dorm room. She stood in front of the door. Room 9. This was going to be her new home from now until she achieves her undergraduate degree.

Taeyeon took a deep breath then knocked on the door.
