''The Heart of Thomas'' is one of the earliest BoysLove manga (its creator, MotoHagio, is a contemporary and friend of KeikoTakemiya, together with whom she is known as a pioneer of the genre). The story starts with a letter from the eponymous Thomas to the young man he loves, confessing his feelings and the desire to have a place in his beloved's heart. Juli, to whom the letter was addressed, appears to be indifferent to it all. However, his world was shaken further by NewTransferStudent Eric, a boy with looks identical to Thomas. The two clash with each other almost immediately and [[DarkAndTroubledPast many hidden problems]] are revealed.
Originally a Japan-only manga, ''The Heart of Thomas'' has an English-language edition in the works scheduled for a [[http://www.animenewsnetwork.com/news/2011-09-14/fantagraphics-adds-moto-hagio-heart-of-thomas-manga January 2013 release]]. The manga was translated by Matt Thorn, a veteran translator who has written several articles on boys-love manga.
