Oasis Keikaku!
オアシス計画
Yagi Naoyuki has always been able to attract any woman he wants, and that has become a constant problem for him. Women take drastic measures when he rejects them, and tired of his endless "women troubles," his parents send him to live with his uncle, Yagi Akira, whose sexuality is rather ambiguous.
At his uncle's apartment complex, Naoyuki meets Yoshiro Kei, another tenant. Despite his usual luck with women, Naoyuki finds himself inexplicably drawn to Kei, sparking a curiosity that challenges everything he thought he knew about love and attraction.
