I can confirm that there is gay content in it, yes. Though I personally don’t like the available male characters for that and my favorite characters are Ziya, Kani, and Nikka.
However, you may stumble into an exception like the following :
While running game code:
File "game/E8_H_M.rpy", line 1137, in <module>
TypeError: coercing to Unicode: need string or buffer, RevertableList found
When that happen, just click Ignore.
