I have Sofia at 10 love hearts and I have already done 2 requests but no..

Try doing requests for everyone in her family. If that doesn't work just do other random requests and make sure you talk to her a lot. I don't think taking her on dates affects anything request wise.

You have to give Sofia what she likes/loves every day and check your mailbox/board for her requests.

Sofia-
Birthday: Fall 7
Likes/loves: Trash items(scrap iron, failed dish, super fail, rare can....)

I know the same things happening to me and I did all that stuff, I don't know whats wrong

Well did you use cheats anyway I used cheats I didn't get it so I started form scatch.but you should tupe in all sofia's quests and there is a FQ that says requests bla bla bla and then you press ctrl + f and then type in sofia and then look what has sofia in it and yea... Theres one in karina and you should do it and yea..... Well also give her rare can which you can find it in sortoora desert and can which is also found there. And I have trouble making from sratch so what also makes super fail ????

To open up requests from a particular character, you must complete all previous requests first. If no more requests occur, complete quests from characters related to the character in question.

For Sofia, that would be - Evelyn & Sherman. Raven and Karina are related as well, but likely do not affect the request progression for Sofia. I suggest you start with Evelyn and if that doesn't work, Raven, then Karina.

You might also simply need to build relationship status with other characters. Again, start with Evelyn.

Worst case scenario is you found a critical bug in the game that won't let you progress Sofia's request chain.

Do make sure you're checking both your mailbox and the bulletin board.

Once you have a characters relationship status at 10, you no longer have to give them items or take them out on dates. Both features are used to build status with that character.
