Wow this is very sweet so far. Im a bit worried for Chizuru for drinking soda though ;-; . And i feel my heart crack after reading that summary. Hope it's not because of that cola. But im glad they met before Chizuru "disappeared". Chizuru got to try cola and Ryota got to meet Chizuru's little brother, Issei TAT
