Kimi to Boku.

Shun, Kaname, and the twins Yuuki and Yuuta have known each other since they were young children and are now entering their second year at Homare High School. However, despite having been friends for many years, their life together isn’t always smooth sailing. And with the sarcastic and indifferent twins constantly teasing or irritating the serious Kaname, it's left up to the optimistic and kind Shun to keep the peace. But no matter their differences, the four boys stick together through everything, whether they’re simply reminiscing about their days in kindergarten, attempting to get Yuuki interested in a school club, or trying to stop the source of Shun's recent run of bad luck.
