With Mo YuMins surprising words, the young man was thunderstruck! He did not expect that the mission assigned to him will include being a fiancee. 

The young man spoke after recovering from shock, but he was immediately interrupted by Mo YuMin. "What?! Why.. Wait... Wait.. I don't think..." 

"You can't decline" Mo YuMin said with a warning glare before he continued. "This will be temporary until someone meets the qualifications to be her fiancee" 

There was a sudden silence that covers the room, but there's a confusion and uncertainty that started to cover on the young man's mind. "You'll have a trial for her fiancee?" 

"But... How can I pretend? What if she kisses me? Does she know? Did she agree to it? What about..." the young man continued to ask with a troubled heart. 

Mo YuMin immediately interrupted the young man as he doesn't want to explain anything. "Your asking too much, don't forget you made an oath"
