Yeah im calling it. Rin will still love Chizuru and will eventually find out. Makoto cant help herself from hiding such revelation and will tell Rin. Rin will try to Elope with Chizuru and then Tragedy occurs hence the "bad ending" people been talkin about. Im Excited to see but there is no englsih translataion past chap 141. I may have to use some translator tools then...
also Looks like maybe Chizuru still being a virgin is Ohtori's punishment to her I guess? Rin still hasnt seen Makoto's Stigma right? I think that Rin seeing it finally will be the trigger for when everything falls apart or goes the path I said above.
