Haha! That is so funny! Muttering with huge blush and he can't hear a word of it! XD
More grammatical suggestions:
Panel 1: It could be 'If I find him alone before the show I'll apologize!' or 'If I find him alone before the show I'll give him an apology!' For the unfinished text under the bubble is it supposed to be 'That is so unli-' As in 'That is so unlike me' ?
Panel 2: I think it would read more naturally as 'I wasn't serious!' or 'I wasn't actually serious!'
Panel 4: 'Failed at trying to leave without being noticed' or 'Fail at leaving without being noticed'
Panel 5: 'To be honest, there's a little blue here and there, but it's unlikely someone would notice it!'
Panel 6: 'Sorry... I... didn't understand a single world of what you've said!' or 'Sorry... I... didn't understand a single world that you've said!'
I think it would sound more natural if he said 'can you repeat that?' instead of 'can you repeat?'
I love this page so hard! It's so cute! :3
For grammar, it should be "word", not "world" in Panel 6. Just so you know.
You are soooo awesome! thanks for help!
And, in the first panel, seems like it is unlikely (i even dont know because a friend translated to me).
but i put improbable.
and thanks again! =D \o/
thank you I'm glad! Yeah using improbable makes it easier to understand whats being cut off. And sorry about writing 'world' instead of 'word' haha >.<
