An epistolary
Of all the writers Mason talked to, Lea was the one who stole his attention the most. Even though they only talk through online and not in person, he feels that she is a good person. He was very impressed because of her writing skills and the ease with which she spoke.
He courted the girl even online. Until she also answered "Yes". But as their conversation and relationship lengthened, the woman became a big mystery to him.
Until one day Lea suddenly disappear and it lasted for several months. All of her friends said they didn't know what happened to her, she came back after the 5 months of dissapearing, but it didn't seem to be the Lea she used to be. It seems to have no memory.
