Sharing story ideas for Katai/Tadano

Let's share ideas for Katado stories~!
I feel that we have not enough ffs with them. I probably make oneshots or full stories on ideas I suggest here, but I'll be very glad if someone colud do this faster or better than me. It also would be great to know what fans of this ship think and want to see/read.

I allow users and authors publish my ideas on other sources and/or languages without asking for permission.

Ps. 2nd idea will become a ff

So I let you use my ideas if you please, but you can't forbide me or other people not to use them afterwards (of course I mean ideas only).
