About I Thought I Knew You
I Thought I Knew You is a youth romance yuri visual novel about a second-year university student looking for his first girlfriend. At a welcome party for new students in his haiku seminar, he meets a girl who says, “I know your secret.” Your choices shape the ending as you explore the characters’ dependence, obsession and longing for the dead.
The characters
The protagonist is kind and considerate toward everyone, but feels self-conscious about never having had a girlfriend. Aoya Itsuki, a first-year student, is difficult to read and somehow knows his secret. Suiren Shiratori is a beautiful, kind and widely admired second-year student who appears to be secretly meeting with several men. Midoriko Kasen, a bright and energetic third-year student, loves the Sengoku warlord Araki Murashige and is not particularly good at getting along with people.
Routes and endings
You can romance three heroines across routes that take about 20–45 minutes each. The story contains approximately 40,000 characters and over 16 event CGs, with eight endings. Completing all the endings unlocks three special grand finales, each with a hidden surprise.
A male character appears only in Suiren’s route. He does not interfere with the yuri relationships, and his face is never shown.
