Which Series should I continue? (Pixiv Fanbox)

Since I began doing 3D TSF stuff with Koikatsu, I started a lot of different series, which got forgotten over time. Now I got too many series and I can't keep up with them while doing illustrations/single projects.

The reason why I'll only continue 1 series from below is simple. I'm still doing "Playful TSF", "TSFVR" and "Idol Search Project", 3 other series I'll continue. But those 3 are a bit special.

-Playful TSF is a series I seriously enjoy making.

-TSFVR is a series only available for Patreon/fanbox

-Idol Search Project is a series only available for Tier 3 supporters (fanbox or patreon)
