^Just at a glance Sunshine episode 10 seemed gayer to me but since I don't have the full context I can't say for sure (i.e. I don't know how much these two were set up as a ship nor do I know how this was followed up on. Sunshine had some set up for the ship but 0 follow up which diminishes the gay factor significantly)
Either way it's certainly gayer than SIP.
^K/DA is classified as an alternate universe, so technically Ahri x Sona in the "main" universe needn't be mutually exclusive with any kind of pairing she has in the K/DA universe
