The main character is a bit of a neat freak so when he comes out the door for school one morning with a stain on his shirt (something like that) his best friend thinks it is odd and points it out, the main character is actually possessed by the ‘ghost’ of a girl named Mina, who is in love with the best friend however the friend is secretly in love with the main character and hides it…anyway long story short, Mina possesses/convinces the main character into seducing his best friend so the main character goes over to his best friends house (they live right next door to each other, so he can just climb from one window to the other) but the friend wakes up, he still thinks it is a dream so when the possessed main character is hesitant to just hop into bed with him he's all like ‘whats wrong? we do this every night’ and bam main character goes oh my god he likes me, they bang and then the main character leaves and everything goes back to normal for awhile but eventually main character somehow finds out that Mina is actually a guy who was in a coma that has now woken up and goes to the same school as his best friend, main character and best friend proceed to get together (I think that they might be cousins) also when Mina possessed the main character he made the main trip and fall into the best friends arms and then acted all flirty in the main characters body so of course the friend blushed and all
