Something found in the inner rectum, with a disgusting smell that is surprisingly satisfying. The human manifestation of such a thing, would most definitely be a pervert. A pervert who likes to touch the Koseis of other men.

"Ew, get away from me perv!"

However, he stopped playing the piano for 2 years due to the death of his mother, Saki. But all this changes when he meets Kaori Miyazono, a young violinist, who tries to get him to play the piano again. And so Kousei, leaning on the one he loves the most, surpasses some of the most difficult moments of his life.
Unfortunately, all great things must come to an end, and he would face heartbreak once again. When Kaori, the love of his life, undergoes surgery in an attempt to prolong her life, so she could play one last duet with him. And she does, the 2 lovers play one last duet together, before she leaves him, forever...
*Sniff sniff*
At her funeral, his parents hand him a letter, addressed to him. And he reads it, he learns that Tsubaki, his childhood friend, loved him, however, the only 2 that didn't know were Tsubaki and himself. And learns that Kaori told one lie, she loved Watari(Hence the name, Your lie in April). However, his biggest and perhaps most devastating surprise, is this passage:
"I’m glad it was you."
"I hope this reaches you, Arima Kousei."
"I love you."
"I love you."
"I love you."
"I’m sorry we couldn’t eat all those canelés."
"I’m sorry I hit you so much."
"I’m sorry I was so selfish."
"I’m so, so, so, so sorry."
"Thank you for everything."

Kosi is a very beautiful personally. A girl that loves with all her heart. She is a lover of music. Kosi can be said to be good in bed. *wink*. She is a hugger and loves to be loved and share love in return. She is a sucker for romantic movies and all things romance. She can be a heartbreaker too, but that is just one of her many sexy characters. She is good kisser and a huge listener. Not to mention , Kosis are very attractive too. They have the ability to lure any guy if their dreams. They are often misunderstood and taken for granted. Anyone will love a Kosi. She stands out and loves to be different and unique in her own special way. Funny enough, she hurts who she loves the most. If you have been hurt by a Kosi , she probably loves you to death. She can be bossy and shy at the same time. Kosis are very ambitious and over achieving. She like to achieve a lot but isn't sad when she doesn't get what she wants. She lives to stand out to bullies and is usually the center of attraction because of her really attractive looks which is usually unaware of. She is always happy and loves to make other around her happy as well. To have a Kosi is to unknowingly have an Angel.
E.g- Kosi is definitely the love of my life.

I'd choose Kosi over anyone.
