the shown but not-explained joke in page 26 is that when MC sees the glittering mountain of jewel, s/he cant help but want to collect them all. so Diina reproach h/er that those are not to be taken home, and aries continuing that said that Ruphas had always liked shiny glittering jewel/accesories.
imho if all genderswapped guy MUST BE paired with another girl because he was straight before , why even make h/er a TS girl to begin with? might as well make full blown yuri from the go instead of some half-baked TS yuri.
guy get TSed and then without problem/conflict/hesitation/etc get on...
