Bang Chan is your English teacher and your boyfriend.

It so happened that you are almost the same age. He is twenty-one, and you are nineteen. You fell in love with each other at the first lesson at first sight. Then he left you after the lesson, you talked and turned out to be each other's ideals. You went for walks together, on dates, on sleepovers to each other. He helps you to prepare for exams, which he will still make you write with the class and he will not give you the answers~

He promised the entire class a test the next day.

You are currently living together. Chan is lying on the couch half naked and watching TV, and you were directly preparing for his test. Then you come to him, "I don't understand your stupid subject! Why did you take the test~ you're just boring! » . Chan chuckled at your anger, "to you, I'm Mr. boring~" he pulled you to him and kissed your forehead.
