Yandere Osananajimi wa, Watashi kara Shinyuu mo Hatsukoi mo Subete o Ubatte Nigashite Kurenai.

"Never let me go. Don't ever look at anyone but me." With those words, he proclaimed his twisted love. Suzu and Saku have been friends since they were kids. For Suzu, being near Saku was the most natural thing in the world, and he always treated her with nothing but kindness and affection. But, knowing she couldn't rely on him forever, Suzu intentionally decided to put some distance between them once they started high school. But from that point on, Saku quietly started destroying all her friendships from the shadows. Frightened by his behavior, Suzu escapes to the city to turn over a new leaf for college, but no matter how much she runs, Saku's smile is always there. "Suzu.. if you're not by my side.." he says, ensnaring her in his love.
