Don't worry touma is not XD. the son is the lil kid that had asthma, the onle who actually looks like the childhood friend at the start of the chapter. touma is his son's friend (AKA way too young for a 40 y-o guy)
Lmaaaoooo he's not his kid, the short one is his kid lol
You clearly did not understand the story... The gay Dad knows who his son is.. And they communicate through email and just recently he gave the son (Rei) a birthday present...
Touma is CLASSMATES with his son.. He was shock cause TOUMA lied about being 20 and was only a high school student...
If touma is really his son, sorry but then I'll think that the old man is stupid.
I mean, even if you're gay you should at least know how your son looks like (￣∇￣")
