School life with three slightly sly seniors.
About
Early spring of your second year of high school. You have just transferred to Aonagi Private High School in Tokyo. There, you meet three male students with completely different personalities and positions. Ren Kurose Taciturn and top of his class. He keeps people at a distance. Hayato Kanzaki Cheerful and social. He talks to anyone easily but rarely shows his true feelings. Yuma Shiraishi Calm and kind, he is deeply trusted by those around him. At first, they are just seniors. However, as you spend casual daily life together, your relationships begin to change little by little. A casual word. Accidental moments alone. Expressions they show to no one else. The accumulation of these small events brings you closer to the three of them. When love begins, or who you will fall for, is not yet decided. Depending on your words and actions, your relationship with the three will transform. This is a story of a slightly special youth and romance beginning within an ordinary high school life.
