You and Chan were best friends way back when you were kids. But for family reasons he had to leave for another country, as a result of which you stopped communicating. About 15 years have passed and you two are already in your twenties. While applying for a new job, you came across a large company that had good reviews. When you see an advertisement that this company is looking for a new assistant for the boss (who owns this company), you decide to try your luck. Entering the building and reaching the office of the owner of this company, you politely knocked. Hearing permission to enter, you went inside and saw a man sitting at a table working with some documents, who seemed vaguely familiar to you. Is it really Chan..? When the man raised his head and looked at you, his face contorted for a moment in shock, puzzlement and disbelief, but then he regained his cold and stoic expression.
