This is the first title by Argonauts, a sister company of MOONSTONE. Keisuke started working this year and is satisfied with his life, since he found a job in his desired field, even though it’s for a small company. However, despite the motivation and satisfaction of living alone for the first time, he did feel a bit tired from it and wondered if he should find a girlfriend.
Then one day, his younger childhood friend Ayame came to his place. Her parents had to leave overseas for work and were worried about leaving her alone just before the important examination period, so they told her to stay with him as he was quite close with their family. Living together under the same roof, they soon began to view each other as more than just childhood friends.
