The novel Finder no Rakuin is part of Finder's canon. But you can not read it here.
All you find here is the one shot included in the novel as an extra. But it is not part of the canon and did not happen in the storyline. Like the threesome or Akihito being a bee stuck in a tree.
And Feilong had no sexual dream about Tao. He had a dream in which Tao growing up worried him - because, yes, he is homosexual (Fei) - and in which Tao confessed his love for Feilong.
Then he woke up and didn't even remember. It was the subconsciousness of a man who thinks that he has never known real love and might not be able to ever find it.
Try and read the novel if you want to understand Feilong. But this manga here is just fanservice and sadly Sensei has done her characters a disservice with them a few times already.
Sorry, I think I worded that badly/did not explain good.
What happens in this dream is Feilong's subconsciousness playing a trick on his mind. It takes his need to feel loved and love, and messes it up with something else.
For Feilong Tao is the one person by whom he knows to be loved unconditionally. And his subconsciousness took this unconditional loving by Tao and put it into a body that WOULD INDEED be sexually available: into that of an ADULT Tao.
Hence an adult Tao expressing his love and attraction.
But Feilong is scared of this, confused by it and even abhors it. Those feelings linger with him even after he woke up and can't remember what he had dreamt about.
He did NOT dream of a sexual relationship with child-Tao. He had a dream of a fictive adult Tao, and that dream was much more about his need for love, or hearing someone say "i love you" and meaning it, and it was less about sexual desire.
And then again, it is non canon, so can be disregarded.
He doesnt have sexual feelings for him wtf…. 1. It’s a dteam not a fanatsy. 2 tao is a full grown adult and could as well be any man fei saw in the street. 3. The dream is a manifestation of fei fear of change and concern over tao obsession for him and him growing up’too fast. Jee i know this manga is not very deep but’thatbpart was clear at last
i can not stress enough how much i hate this, it ruined fei long for me. him having sexual feelings for tao is super gross, because tao is a freaking PRETEEN, and fei long was the one who raised him, so him seeing tao in that light is just
