I recommend to just shill out those measly 9$ for a monthly sub. You don't only get access to the Liebling! series but every other series on Toomics as well you know.
And if any sort of "social stigmata" is worrying you (parents or friends finding out whatever) then rest assured, Toomics mainly features non R-18 comics and non-BL comics. Liebling! is actually the only one there that is R-18 and gay-themed.
Plus I very much doubt that there'll be any new chapters shared online ever again. Toomics mentioned to pursue legal actions, looks like they did and it worked.
