Oops, damn, I answered the wrong message from you, hehe..
As for your question about when there will be a new update of Lucas, the author has not yet said anything about it on his Twitter. Logically, there should be Lucas after Lei, because the last announcement was directed at Oscar, but because there are a little more chapters in Lucas's route, he is a little ahead of the rest, at least that was before.. Now I'm not sure, because I don't remember how many chapters in the route of each character came out at the moment, maybe the remaining two boys have already caught up with him, maybe they all became on par, or maybe they overtook him
But if Lucas has more chapters, then I think there will be an Oscar again after Lay, but that's just my guess.
The author has been ill for a couple of weeks, so the release of a new assembly (that is, the Lei assembly) is delayed, postponed until later.
I hope that my answer will help you at least a little
