You know, I could have done without the last chapter and the extra, that's where Yoshiki's character reveals itself to be a psycho yandere bitch. Up until then he had been the kind, carefree partner that might have been good for uptight Tsukasa and then it's veering into psycho land - stealing his girlfriends in hs and then abandoning them? poking holes into condoms?? bitch what. Tsukasa is turning into an omega against his will and Yoshiki is secretly plotting his pregnancy out of 'love'.
