3(Blue Lock)

An Au where after Blue Lock players' game with team World Five, the members of the last team get interested on Rin(who is my baby) and decided to take him under their wing.

They discuss with Ego about them being allowed to visit Rin and train him which Ego ends up allowing after a very long talk(how they convinced him is up to the writer) and the next thing Rin knows, he had been kidnapped by the group.

Slowly Rin opens up to them and accepts them as his friends(and maybe older brother figures?) and whenever he has free time, he hangs out with them(in person, by text or video).

At first no one in Blue Lock noticed this until the game against Japan U-20 where Pablo, Loki, Dada, Luna and Adam go to watch a cheer for Blue Lock's team and later when they win, while everyone congratulates Isagi, they all run to Rin and start congratulating him and saying he should have used this or that thing they taught him but that he had been amazing in the game and Blue Lock wouldn't have won without him there(I would be very happy if there was a bit of jealous Sae, especially with Luna being close to Rin).

How this changes anything eles(Rin would still go to PXG), what ships there would be, etc is up to the writer.
