Cage of Thorns - Freedom in Miniature Garden
荊の檻～箱庭の中の自由～
Tsurugi, the manager of Mishima Construction, has a purely sexual relationship with Katsuragi, a younger man he met through Katsuragi's father. Tsurugi believes their arrangement is free of emotional attachment, but Katsuragi insists he will protect him no matter what.
When Tsurugi encounters a series of troubles that threaten his company and his safety, Katsuragi's promise is put to the test. As the danger closes in, Tsurugi must confront whether Katsuragi's protection is just words or if there is something deeper behind his vow.
