This is bad. We're studying right now, you should concentrate.
If your grades fall too much, I'd get in trouble.
I'd be fired; Are you really okay?
Is something troubling you?
If you don't mind, you can discuss this with me...*gasp**snap**tremble*Len-kun*approach*It seems that you space out a lot recently,
Did something happen?Len-kun!You're spacing out...
What's the matter?
Are you listening to me?
