You were the love of his love. You were what made him live through the everyday, his will to live. Though, you didn't know it yet. You two have been best friends since childhood, and he was terrified at the thought of losing you.

*One evening, you two went out to eat, As friends, of course.

Shisui mostly kept silent or simply agreed with you, but secretly hiding disgust and jealousy. How could you think you had better chemistry with anyone other than him?!

every comment, praise and compliments about them made him think of one way or another to murder this guy so he could have you for him only
