HUGE NOTE*"chest balls" refers to boobs. that is all.
Also, next chapter and on will be hinted rin x shiemi.
While opening the door to his classroom, Rin held his breath. What would he find just behind the old wooden door? Was it going to be sorrow or joy? Rin braced himself for whatever was about to come his way but. . . Nothing? Rin opened his eyes to find an empty classroom and lights on. Phew, I'm actually early, gives me time to put on my disguise. Finding the darkest part of the classroom Rin sat down and grabbed a long cloak with hood out of his backpack and tied it on. Nobody would know that it would be him unless they actually came up to him, which wouldn't happen. Only a few minutes passed until the hearing of footsteps could be heard. Rin tensed, was it class time already? What felt like minutes to Rin were only seconds. Soon, the classroom door opened and in stepped a few of Rin's classmates, Bon, Shima and Konekomaru. By the time class started everyone was in their seats and had paid no attention to the cloaked figure in the back of the room.
As class went on, Shiemi looked behind herself multiple times. Nobody but her and Shura (who was teaching) had noticed the man in the room. Rin looked the other way, his hood covering his face, he could not allow anyone to de-mask him, no matter what.
Something felt off to Rin. Shura had stopped speaking and the room was silent. Rin lifted his a head a small bit too see what was happening when he caught glimpse of a big pair of "chest balls" and a small bikini. Shocked, Rin fell off his chair and onto the floor. Trying to pull the cover of his hood down he realized that it was caught on the chair and no longer covering him. Scrambling off of the floor to unhook his cloak he was grabbed by the back of his shirt and dragged out of his seating row. "Ooooh! Lookie what I found!" Shura said, with a mischievous grin on her face. Struggling to free himself, Rin felt like people were staring at him. He was right, the whole class turned around and gasped. Rin looked up to see the shocked faces of his friends and stopped fighting Shura. "W-w-wait… Rin? What are you doing here?" Shiemi hardly managed to get out. Not knowing what to say, Rin just collapsed onto the floor and let his head fall. What do I do now…?
