There is no rape tag - I think, you're thinking of Myreadingmanga.
Well, I see this tag clearly...
You mean the warning that is on everything yaoi no matter if it contains anything rape, gore etc.?
I don't see the word rape anywhere, even in the may contain general yaoi warning.
Can you see the 'Top tags' list on the right? Yeah, there is a word 'rape' there.
Just look at Top Tags in the right side of the page.
Thanks, rarely look at those tags though (and sometimes the tags don't fit the manga).
For the people who commenting on the rape and rating an [incomplete] work based on one chapter, please take note of the tags and notice the RAPE tag just in case you didn't see it there or in the comments or the discussions. Don't like, don't read. I'm not usually one for romance based on non-con or rape, but like View Finder, this manga seems to really dole out the rape in the first chapter and the rest seems (and please let me stress the SEEM part) to be consensual. I'm only basing this one what I've seen in raws and there seems to be a lot of lovey-dovey moments down the road. I personally enjoy adoring, dog-like seme characters and I will be looking forward to its future installments.
