Rot [English translation]

Over us, grass grows1

It's all shards - you see glass

Your handshake is now strong and heavy

I saw red - now I don't see anything

I saw red - now I don't see you anymore

Above us, a false star

I've been chewing on the core forever

It will scarcely move self-sufficiently

I saw red - now I don't see anything

I saw red - now I don't see you anymore

1. I think this is a play on the German idiom 'wait until the grass grows over it' basically meaning 'wait until this stressful/significant thing has cooled down (become less significant)'. This line may be best interpreted as 'we've cooled down'. Or 'our relationship has cooled down'
