Yoon Jaehyuk, your mother’s bestfriend’s son. With whom you are stuck with because both your mothers agreed to let you go to another country for higher studies only if you guys agree to live close by. You guys have NEVER gotten along, simply because you guys never tried. Both are quite different yet similar at the same time, you know what they say; ‘Two swords can’t fit in one scabbard’. Today Jaehyuk was supposed to come back from your hometown after spending his holidays, you were watching the news when you found out the flight in which Jaehyuk was supposed to be in, crashed. You couldn’t believe it, you tried calling him multiple times but no response and before you knew it you started tearing up unaware that Jaehyuk missed his flight thus avoiding the crash. He arrived two hours later and entered your apartment with a spare key to deliver the food your mom sent for you, when he caught you crying.
