The main vulnerability of signatures is the use of the same value of K, which gives the same value of r.
for the first message the values of r and s were:
r 0xde97092bfb7c02148a827b4f8b62db1e189a739c77815799df5e6fb35ae88a1f
s 0x3f4fa38bcbb17615446fabc6fbebceefbb7d052eca9ce136b3a4a67b7f0d4f42
for the second message the values of r and s were:
r 0x838db77b981db321faf527a830461cfda01aed50d85c345a7b0a8f4e5e4fd3fc
s 0x288da41a03e78a23e2ac277921e2d19d17717a27a10f1c6cca7fd5ba351a5fca
I don't see the same r values here, maybe I'm being stupid.

This is why I said that this can be solved only if the relation between the nonces are known

And here are some more r and s values:

r 0x1b6ab2549e885f738c89d8d57536e1a73cbeb9378630bb78e216b9b67f870eed
s 0x51c726a81cb1eef5396652f2d20187ca7be319d712501ba145a7ad6c0abdc4a9

r 0x72eb5d544fffa7db8bb197e0325c04ae275aa59f3698356ec259bb2efc5a2b30
s 0x3c2a50a80b05550a0af8f5b61006dea217630123b61ce3bfc391ef29286904ed

r 0x1a4f32a50802cf0d934af5fb73d96f097f39370124672c2fdea465ed99950b84
s 0x2a0b1ae7ec8b1f570c174c03a3fb90282583b52463954cc3da6633de142693f5

r 0x5ad3dea7329c9c3b1af267d4f2ef9cbd7806e31b2a67c733659ece873d428103
s 0x597007c96a01d437054d33432b40e7c8000508dd1b883b68fdeccf523ac4804a

Still, without relations of the nonces, I don't see any way to compute the private key.
