There is currently no further story for them, but it might get continued in the time skip events. (As with many others)
The story is intentionally written in such a way that players could think that the "dragonic" might be Ryen, and imagine themselves in that event, but Ryen and the two girls don't regonize each other, so it's not actually him.
could have been, but many events are now becoming involving other characters (male dicks off course that's the issue) this is converting slowly into a fuck fest and not remained a pure harem now, in start i also thought those were memories of Ryen, but nope, then gf of Brad scene, then that Assassin women scene working for dorgania govt. As once a wise man said, more than 1 dick in a harem is too much dick, here we get uncountable and many male dicks too.
