Wow, where did you get the idea that Thea was Grossebustenhalter's daughter?
Great one, Otto's too sensible. ;]

He was alone with his crush in her home, which has her room, which has a bed-‘Bad thoughts, bad thoughts’. Otto scolded himself.

Hehehe. That made me laugh!
Brilliant!

Wow- all this for me? XD I loved it.
I find this to be not OOC, because I feel that Thea would like the leap, after she got over the initial shock. She would be the type to want it to move fast. And Otto just wants Thea, so... there. :3 I adored it/you. :3

Very good! I like them together. They both need someone. How cute. Good writing! :D

1) I am very gld to see that you are back! I hope for some more fic soon.

2) This was very good. I think you could even turn it into a two shot if you'd like. lol
