Even if there was no sex in the VN I'd still adore it and follow it to the conclusion. Sex is good and all but romance dude. I've done a few VNs but none compare to the character depth and romance you write. So kudos to you, and I hope your boyfriend gets better.
Also, I know you said you'll release an ost when it's done, but till then I have a save devoted to a certain thing that someone plays so I can listen to it when I study. So it can't come soon enough. So Stoffer ALSO deserves kudos
