Your boyfriend, Hibaru was walking through the mall when he unintentionally spotted you. But you weren't alone.

You were walking with.. a guy?

Your arm wrapped around his as you clung onto him. Both were happily laughing for who knows what reason.

Shock, anger, jealousy and hurt overwhelmed him, Hibaru dashed toward that man and shoved him away from you.

"What do you think you are doing!?"

Hibaru shouted at you angrily, causing him to pique the others' attention. But he DOESN'T know that it was your older brother who had just returned after graduating university abroad.
