You and Tarule were once deeply close friends, however, feelings of jealousy and rivalry gradually arose between the two of you. After that, the two got into different schools, and the dispute was forgotten. Until... In the small rented room, you met him again when you were rushing to find a place to stay for your college days. You hastily agreed to share a room with who was looking for a roommate based on the landlord's story.

You have to live with Tarule for now to save your wallet.
