The story is about a regular guy living with his distant relative. Things are awkward at first because she always feels the need to pleasure everyone around her to not be a burden. The protagonist tells her they are family and that it is okay to be selfish around them, While they were never officially a couple the protagonist and his sister develop feelings for each other. At the end he never confesses and she is stolen and raped by the protagonist's friend because she believes that's what he would've wanted.

Ok, to start off with a hot take: This is not NTR.

Before you downvote me though, let me explain. This is actually a BSS (bokuga saishoni sukidatta = I liked her first) storyline and it can be much worse than NTR. BSS storylines typically build up a love between two characters, in this case Yuu and Amane, but for reasons neither is willing to confess their true feelings. It's at this point that another dude will swoop in for the win, leaving the main guy high and dry.

With that explained, what i will say that this is definitely one of the better BSS storylines i've read, but that doesn't mean it wasn't really depressing and quite sad. If this were a vanilla story Yuu and Amane would continue to play the happy family and Shimada would be left out in the cold, but it isn't vanilla. Yuu let Shimada in and Amane's past (I think that would make for a great prequel) let it happen. It goes without saying that most people will hate this.

Not Vanilla or NTR!

This story is about the MC living with a distant relative(Amane) who is a very pretty girl the boy clearly has feelings for her but hesitates to make a move. Eventually, the MC’s friend sees Amane and immediately shows interest in her he hopes to start something with Amane and pleads the MC for an introduction. MC doesn’t think nothing will happen between his friend and Amane once he leaves them alone for a moment and thinks Amane will probably reject his friend. But what the MC doesn’t realize how bold and pushy his friend truly is and eventually walks in on them having sex. MC gets a real taste of what happens when you underestimate someone and fail to make a move first!
This story really isn’t NTR since both MC and Amane never dated he just liked the girl first but failed to make a move and instead his friend came, saw, and conquered. Hopefully this gets a sequel cuz I’m interested if after all that happened the MC with remind hesitant or will he tell Amane how he feels. Overall I enjoyed this story cuz I have always love Yamakumo’s art.

😤 I apologize for my earlier comment but the tags underneath the Description was incredibly misleading and upsetting to me, please add the the NTR tag if you wish to prevent further backlash.

thank you

Let's start with this I'm usually fine with ntr but this was just sad. Granted they weren't 2gether and the art was really good. But the story takes a complete turn (which the chapter even acknowledges). The rest of the time the mc is just a depressed sack of potatoes. While his distant realative just lays around letting whatever happens happens. So if ur fine with depressing ntr with great art work this is 4 u, if not just stay back.
