In terms of story, that one is kinda flat. The male MC’s childhood crush married his elder brother, and now he’s entering adulthood while she’s an unhappily married woman who rants her husband doesn’t pay attention to her and hasn’t touched her in more than a month. They have a little drinking party, the booze does its job, she deflowers him with a naughty smile. Ending in the form of a question mark.
But the good part was with the art, anyway. It looked great, and it was fully decensored to make it even more awesome. Simply check it out with a few pages, and see for yourselves, how about it? ^_^
It’s been scanlated by CopyOf, many thanks!
