Did you do the plan to destroy Tanja? If you did, then do the nice guy path not the ass hole one. Doing the ass hole one will piss lucy off and end her arc. Do the nice guy option and you can take tonja on a date where lucy is there and we'll it's how you gget lucy to fall for you.
Absolute masterpiece. Great job to killer7 for this work of art. I've laughed, cried, thought lewd thoughts, but regardless sucks that tonja arc is probably not going to continue. What a good pet she is.
