>>21294721Here's an important secret about having an oshi that most people won't tell you.
When they choose you, and that whole "oshi-fan" bond is made, it's with a certain person in a certain point in their life. If you're very lucky, you were chosen by someone that's going to be who they are for a long time. But sometimes, that's not what happens, and then you don't have an oshi anymore.
Look at some (NOT ALL, some) tatsunoko. They had an oshi. By all means, you'd assume they still do. But they don't all have one anymore, even though, you'd think, right? But no. Because it's different.
It doesn't have to be that drastic for the same kind of thing to happen to anyone. Maybe you'll be picked by someone else. Maybe that was that, and you've had your fun, but it's over now. Maybe it'll come back, and the feeling you're having right now is just an aberrant in your long history with them. But who knows?
Don't be surprised if it's gone, but don't be surprised if those feelings have a new start, too. Just, follow the wind. You may be stuck in wanderlust for a bit, but your heart will guide your way to the right place in the end.
