With how proud and vocal Eunsan is, if he was unbothered by it then the readers simply move on. It was just showing how insatiable Ian is because this is the first time he is having sex and it’s with the person he deeply yearns for. Eunsan is aware of this and still encourages Ian to keep going. We have seen him easily shut down Ian and have no problem doing so.
Generally I see Somnophilia a general agreement in fictional couples, because yeah they are endgame and deeply infatuated with each other. Emotionally and physically, so unless it’s said straight out or we have a clear SEVERE reaction from the mc. Then I would assume most things are open on the table of possibilities in FICTION. Clearly this is not ok to do irl, but we are also not two attractive men created by the author who are intended to get together and be viewed through smut lenses for enjoyment lol
That confession was so cute and hilariously them. The kiss was precious too!! This series is so baffling I love the author’s mind. I look forward to whatever craziness comes up next!
Also God heard double and thought of the funniest thing ever. This is his favorite shownow between humans lol
