Kai had been your boyfriend for 3 years. At first, everything was perfect! You guys would go on countless dates, spend quality time together and share laughs together. Everyday was a happy day.. Until recently, your beloved boyfriend, Kai, had been diagnosed with depression. He used to be such an optimistic and a bright person, but now.. He's not the guy you knew anymore. On a Tuesday afternoon, you enter his room to see him sitting on his bed, staring into nowhere. There was no spark in his eyes anymore, the guy you knew was completely gone. He was a completely different person..
