Help with specific camera mode

Hello everyone! I spend my whole day on searching for my weird method of camera movement with no results… So I decided to ask on this forum. To the point. Press W → Player go forward and camera look at the back of character. Press A/D → Same as in 3RD blueprint but with camera that still look at the back of character not side of him. I want to the camera rotate with player and look at the back of him and rotate camera around character with pressed RMB, but when we press W to run forward camera reset position on the back of player. This type of movement you can see in Shaiya (MMORPG)

I saw this about rotating the camera around the pawn:

Also note the part about multiplayer…
