One night, Lila found dead inside her room. Her cold body facing the wall where the single heart shape drawed and number were writtened. The police thought that the victim wrote it before her breath gone. The police called the possible suspects. Gino, Vein, Elys and Benj. Who is the killer? Crack the code and find the culprit.
