The story revolves around a young male student who harbors an intense, unspoken attraction toward his aloof stepsister. Because she always appears to look down upon or despite him, he keeps his distance while quietly observing her from afar. To cope with this perceived emotional rejection, he redirects his attention toward external sources of escape:
The story progresses as the protagonist's interactions with the school instructors lead to a series of complications that ultimately force a confrontation at home. The narrative's central turning point occurs when the emotional barrier between the protagonist and his stepsister begins to dissolve.
