That is what upcoming Summer Bubbles (now renamed Summer Desire) should be instead titled as.
I mean, here is the description from the book SD is based on in which our heroine first meets her stepbrother (and eventual boyfriend) translated a bit roughly but still legibly by a kind person on AF:
The young man sat under the blooming oriental cherry tree, his black jade hair had a diluted luster, the skin at the back of his neck meticulous like beautiful china...
"From now on Luo Shi will live with us. He's your older brother, you guys must care and love him, okay?" At dinner time, Dad's chubby face was full of smiles, his right hand patting the back of the youths hand, he said to her brother...
"Luo Shi suffered a lot in the past," Dad painfully looked at the youth, then turned towards her. "So Xiao Mo, you have to be like dad and take good care of your brother."
Yi Xia Mo measured up the youth sitting by dad's side again. His name is Luo Shi, 16 years old. No matter in the school or on television, she's never seen such a pretty boy. His skin is as beautiful as the oriental cherry blossoms in the courtyard, (his) pupils are as pitch black as agate, (his) black hair has a silk gloss, despite his clothes being a little shabby, when he wears them they carry a type of princely boastful nobility.
Luo Shi is also watching her...
When she first saw him, there was that alarming feeling in her heart. Under the blossomed oriental cherry blossom tree, Luo Shi's beauty was like the alluring evil spirits in picture books. He was too beautiful, a youth being like that was a very scary thing.
Ahahahahahahahaaaaaaaaaaaaaaaaaa! Welcome to the house of fakecest! That is what happens when your Daddy randomly shows up at the house with a hot stranger and declares he shall be your adopted older brother. Bwahahaha.
In other news, I am so going to be rooting for stepbrother in this love triangle. As Xiao Mo's other choice is the ex-boyfriend Ou Chen. Seeing that Ou Chen was charming enough to act out his jealousy of his then-gf's getting a hot stepbrother by using his $$$ and influence to pressure Xiao Mo's dad to drop stepbro back at the orphanage, I am already pissed off at him. Who the hell does that? Oh, not to mention that on the way back from dropping off Stepbro, the car got into an accident and Xiao Mo's parents died and her beloved younger brother got horribly injured. Yeah, it's all your fault, jerk of a boyfriend, WTF is wrong with you! Though I am going to really gloat and enjoy if they have the book scene of Ou Chen coming asap to Xiao Mo after all of this and her telling him it's all his fault and how much she hates him and diaf while he is there kneeling begging her forgiveness. YUM. *sluuuuuurp*
