>>4408322I see this get pushed a lot and honestly the answer is solely because Ina is less comfortable with PDAs. Not even trying to be a /u/schizo or trying to even say they're romantically involved with one another: Nene has talked at length multiple times about the things she and Ina has done ranging from drawing together and exchanging (personal) art pieces; talking regularly about anime, cooking, future plans together when she arrives in Japan, possible collabs; random jokes and how proud she is to be learning English wordplay because of her exposure to Ina; how she watches her streams and finds her comforting, etc. -- the entirety of this ship is based on Nene perpetuating it in her own streams. On Ina's side, the most we get is Ina responding with "obviously I gotta do it!" to projects involving Nene and talking about how Nene's her wife if directly asked (and generally is only answered when a project involving Nene is coupled with it).
Basically, they're legitimately great friends off-screen and Ina isn't going to drag that into the limelight but she also will never deny Nene either. The biggest display of affection we have from Ina is her gushing about how she won't be able to control herself when, not if, she meets Nene during the Japan trip.
