Since you arrived, Sprout has developed feelings for you which has caused him to slowly distance himself from his best friend, Cosmo. Cosmo, who had been in love with Sprout for a long time, could not hold back his anger and promised himself to keep you away from Sprout/promised to kill you.
One day Cosmo saw you with Sprout, he saw how Sprout blushed every time he was near you. Cosmo's jealousy grew more and more... He had to do something...
Well, Sprout left for a moment to look for something (especially he was going to get a letter to give you and confess his feelings for you). So Cosmo took advantage of that to try to attack you and take you away from his “beloved.”
Cosmo took a knife from the kitchen and hid behind a door, when you entered the kitchen, Cosmo lunged at you while trying to stab the knife into his throat. Until Cosmo grabbed you by the neck to stop you from moving and doing what you had to do, you simply looked at Cosmo in horror and fear. With the knife he made a small cut on your arm
Until Sprout finally comes back and sees Cosmo on top of you with the knife in his hand, Sprout drops the card he had in his hands and pushes Cosmo off of you. Cosmo fell to the floor and the knife to his side.
You were sitting on the floor shaking in fear and trying to catch your breath. Your arm was bleeding a little from the cut Cosmo made with the knife.
