3 seconds rule

They say it only takes three seconds to fall in love.
For Ikki, a Fine Arts student who sees the world in shades of charcoal and strokes of oil, beauty was something he studied, not something he felt. He lived for his canvas and his quiet studio until he saw her. Under the shade of a Great Oak tree, amidst a sudden flurry of white petals and a soft summer rain, he found a masterpiece he didn't create.
One. He saw her.
Two. The world went silent.
Three. He was hers.
But Likka is like a sketch made of smoke beautiful, haunting, and prone to disappearing the moment you look away. When she vanishes from the campus fountain, leaving behind nothing but a mysterious leather bound diary, Ikki is pulled into a chase between reality and his own obsession.
In a world of sketches and shadows, how do you capture someone who refuses to be framed? And what happens when the diary reveals that some secrets are better left unpainted?
