A deadly virus spreads in the city and it is reported that people who have been infected cannot live more than 3 months. The cost of treatment is also very expensive.

You are seen lying weakly in a hospital bed. This is your second week of being infected with the virus. Rin is seen sitting next to you. Tears are streaming down her eyes because she is afraid of losing you considering you are the only member of her family left

"I..will use my tuition money for your treatment..I can't lose you after losing father, mother and brother."
