Growing up in a depressing and gray-toned life, he was a taciturn academic master who always hid his adoptive mother's scolding and the burden of life while counting stars on the rooftop; she was a flamboyant and unruly "eldest sister" who used a sharp shell to cover up the scars of being isolated because of her righteousness.
Their first encounter was a collision in an alley, and she impulsively made a save but was treated as nosy by him; the fingertips of the bento touched, the umbrella left in the rain, the crooked smile on the problem-solving note, these small moments were like sparks, smoldering in the ashes of misunderstanding. The booing from classmates, tampered answer sheets, and quarrels caused by anonymous remittances pushed the two away time and time again - he was afraid that she would get into trouble because of him, and she mistakenly thought that he thought she was vulgar. Pride and inferiority were repeatedly pulled apart during adolescence.
It wasn't until the surveillance video revealed the truth and the coincidence of the strawberry candy in their childhood surfaced that they were shocked to realize that it had already left a mark on each other's lives. The starlight they watched together on the rooftop, the moment when he held her wrist tightly to resist her adoptive mother, and the words "I will protect you from now on" at the graduation ceremony finally caused the entangled vines to break out of the ground.
This is the mutual redemption of two lonely souls. In the push of misunderstanding and getting closer, the boy puts away his cowardice of lowering his head, and the girl takes off her sharp armor, and in the gray world, they shine out their own astringent and hot light.
