Ok so Tess is like 12-13 and looks like that like she's pretty like I'm a bit older but I look like a Cockaroch that has been stepped on ⊙︿⊙

Plus you also have to take in the aspect that she's an elf (which are notorious to being beautiful) and a character that was drawn by someone's hand. It's kind of hard to compare oneself to a fictional character. I definitely wouldn't bother comparing myself to Arthur because homie would destroy me in looks.

if the old aunt lady is married why couldn't she just use her husbands sperm instead of stealing yi yun's sperm?? and does her husband know about this? I need answers cuz its either im stupid or stupid

Alright, first aunt is old, she can't have her own child, she can either make a baby from surrogacy by her husband's sperm or by adopting. But both of the options won't give her any right to have inheritance. In their family, first born gets everything, so as jinyao and his first born. It's all about inheritance and not only baby. Jinyao's first born child will get inheritance rights. So basically she wants that. And Bitch aunt somehow got to know that jinyao frozen his sperms. But what she doesn't know is jinyao exchanged his sperms with yiyi's sperms and that's how rourou born. So the remaining frozen sperms were yiyi's, but bitch aunt thought it was jinyao's. So she stole it, and now has baby from surrogacy. She thinks it's jinyao's first born, so she can inherit everything. (but in real it's yiyi's lol)

Since she’s old I presume that she’s already menopause.. if the egg cell is not from Rourou’s mAma, Ima (╯°Д °)╯╧╧
I wish the egg was from Rourou’s blonde ma’am because that way, they can be real siblings. Rourou knew Bighead through his dreams way before anyone so I think there is hope that they are of the same blood.

No sorry to disappoint, but the surrogacy doesn't work that way. Also you can say, aunt doesn't know about rourou, so she didn't have the baby from same mother. But even if she did, the baby would look like yiyi bc it was his sperms. (which actually is gonna happen hehe) hope this helps. You can also search the Google to know in details how surrogacy works.

And I think rourou can see his baby brother not bc of his blood relation (bc there's none, bc new baby is blood related to yiyi, rourou is blood related to jinyao ) but it's more like emotional connection. Rourou sees yiyi as his own father and the new baby is related to him, so I suppose bc of his powers, he can talk to bighead.

Yep that's how surrogacy works. Surrogate mother gets money or whatever they want or decided with whose baby they're carrying. It's like borrowing womb of woman. Surrogate mother don't get any rights of the baby. As it was mutual from the start. So yeah, surrogate mothers won't show at all (neither rourou's nor bighead's)
PLZ THE DOCTOR WAS SOOO CUTE I WAS ATTACHED TO HIM I FELL IN LOVE AND THAT USELESS BISH (whose name I forgot cuz it's not worth remembering)KILLED HIM(´°ω°`)NOOOO
