Gekkouzaka no Hanayashiki
Inspired by ante-WWII western domestic architecture and gardens, Kinoshita Keiko daydreamed up a story about Yukiyo, the gay man who inherited one such home, where he lives with Takashina, his lover, and Yuuta, the son of his ex-wife and the man he once loved, who suffered from depression and commit suicide many years previously. Filled with remorse for confessing to his late friend, and muddled by disappointment and unresolved grief, Yukiya swings wildly between seducing and rejecting Takashina. Things remain in stasis until Yuuta makes a confession of his own, summoning Yukiya's protective instincts. A slow building emotional simmer with some very beautiful watercolour drawings.
