By some coincidence

Presumably by some coincidence.

Haven't had the opportunity to meet yet to leave

In any event, spring has darkened its tones

Pitiful for us alone

Possibly it was only a mishap.

Haven't had the opportunity to communicate yet need to leave

Indeed, even the new frogs are groaning

Pitiful for us alone

As though by some coincidence.

I haven't seen your face at this point

Indeed, even the recently grown grass likewise covers up back to the ground

Tragic for us alone

Truly by some coincidence

Haven't had the opportunity to bid farewell however to leave

Indeed, even the earth was by and by covered with ice

Pitiful for us alone

It was really unintentional

It's really short

Coincidental flight

Only for a periodic farewell
