Base on my research Toma-kun doesn't have a girlfriend, maybe because he is busy of his acting career and don't have spare time for the girlfriend stuff....
i've read in some interview, that he doesnt have time and intentions to date now a days...
but in the future maybe...XD
if he aply his "knees desires" the choice will be a little dificulty in japan XD so...come to brazil XD auahuahauauh
ok ok joke joke XD
but i dont know anything about a girlfriend...but my suspicious about Shun e Pi is big XD (ok im joking again XD)
