y'all gotta calm your tits and just appreciate the proactive MC going after her depressed vampire girlfriend. No need to to taint it with drama from other, completely unrelated manga/doujins/etc. And get off your damn high horses - good artists don't just stick to "safe" topics and scenes and plots and pics or whatever. In fact, any who do stay safe and don't ever produce anything illicit are either lieing and hiding the illicit stuff, or they aren't good artists. You don't improve and grow as an individual in a discipline which requires you to break molds by staying on the beaten, censored path.
If you can't handle reading that stuff, don't read it. That's what we have tags for. Read those first. If you're so effing sensitive you can't handle reading a "safe" work by someone who also makes "unsafe" works, then you may as well just stop reading anything at all besides Dr. Seuss stories.
