it's obvious that Christoph loves Ryan. the fact he's resisting the last order to return is enough evidence of how much he loves Ryan. The real question is if Ryan loves Christoph as a son as he claims to be, or it's actually more than as a son.
the last ch61-62 are breaking my heart for Ryan and Christoph. Ryan should live together with Christoph. tbh. TT - TT;;
I think that Ryan, with a little bit of effort, could've loved him romantically but he decided to carry all the weight by his own :'( Idk what's happening with Ryan (maybe He IS dying) but I agree with you, if I were him I'd take Christoph with me and live the time I've got to the fullest, maybe its a selfish thought but love has lots of those.
but what if Christoph loved Ryan?
we'll never know now ;_;
