Steins;Gate Romance

I'm a huge fan of the subplot (or actually the main plot) romance, and i heard there is some kind of spin-off VN that has some focus on this content as im hungry for Kurisu x Okabe, i never played the OG VN too due to it not having the anime OSTs from what ive heard (Suzuha, Christina I and II, Believe Me and Farewell).

I almost played Elite but i heard too much content was cut from it, before even trying this Spin-off, do you think the actual VN adds a lot more to the romance than the Anime ever did? If so i might give the VN a try too as i mistakenly bought it on Switch 2...
