This is the life of Lee Sung, when he was 19, he started his High School, Fourth Semester. He is a straight B student, and he is a little shy in new students. Since Lee Sung had heterochromia, he can focus better even if he had so much distractions. (Heterochromia is the different color of the iris from your eye)

He had to burrow some of his mother's money, since he ran out of rice for his lunch.

He took 500 won, that costs half of his lunch set from the cafeteria. Lee Sung waited the bus, and he almost had bumped from the door because of his running. Few minutes later, the bus came here, and he doesn't seem familiar going to a new home. Well, Lee Sung tried to be calm. He whispered to himself: "A new student huh? Guess we will run out of empty seats from our class today, or maybe?" After the trip, he got off the bus, and got to class A31. He had met the new student in his class, he whispered to himself again: "Guess I was right, we will have no more empty seats today." After introducing his name, that was Gyeo Woseok, he had seen Lee Sung. His heart melted and fell in love. After the introduction, he just knew that Gyeo will be Lee Sung's seatmate in class. What would happen next?
