Confrontation Road "Brothers and Sisters" High attack and low defense girl × low moral pervert brother One day, a request for help was posted on a social software. [Help, what should I do if my brother's xp is pseudo-orthopedic? ] Netizens responded quickly. [Everyone has xp, what's the point, respect personal xp] [The building manager is too lenient, your brother's xp is none of your business] […] [But is the poster male or female? ] [Female] [Hiss... How did the poster know about my brother's xp? ] No one replied. Later, someone else came to comment. [I would like to ask, are the original poster and my brother brother and sister? ] […Is not] [I seem to understand] [I seem to understand] [? ] … [No one replied to the original poster? Don't even say anything? ] [That is, if you don't say it, then I won't say it either] [If you don't tell me, then I won't tell you either] * Chen Qingnan never thought that the bloody misunderstanding in the novel would happen to him. When I was eighteen years old, I was found by my biological parents. Even though I didn't want to, I couldn't resist the temptation and decided to go home with my biological parents. On the way back to the city, she learned that she had an older brother, who was not her biological child but better than her own. Her parents hoped that she could get along well with her brother. Chen Qingnan, who was dependent on others, naturally agreed honestly. I just didn't expect that she would faint at the first sight of this brother... "Sister." The man in front of her was cold and dignified, and handed her the gift with a friendly smile. Chen Qingnan took it with stiff arms, and all the sounds were swallowed up by shock. There is only one thought left in my mind—— Who can tell her why this brother looks exactly like the online dating partner she unilaterally broke up with? ! ! Later, when Chen Qingnan went to college, she became even more distressed. She registered a small account and posted almost all requests for help. One day, as usual, when she was approached by a brother who was like a dog-skin plaster, her sense of morality made her sober and scolded her, but before she could say anything, her attention was attracted by the mobile phone in front of her. Shang Xingyuan held the person in his arms with one hand, his warm breath caressing his ears, and with the other hand he slid his phone in front of Chen Qingnan. The content of the request for help slipped in front of her eyes, and a bewildering voice came from her ears: "Sister, the title is wrong." "..." "You should write, what should I do if my brother has a sexual fetish?"
