「僕、幻滅しちゃったなぁ」

“I’ve become disillusioned.”

[tn]What Proxy is disillusioning themselves from is a bit unclear. Mayhaps Proxy didn’t expect Seed to shove her feet towards their face? But then disillusionment implies a disappointment from having the held illusion or expectation shattered; contradictorily, Proxy seems to have a foot fetish (based on Seed’s dialogue here), implying they’d be happy with this.

Maybe this is Seed? This also seems unlikely, since the continuing post has Seed gladly showing her ass and feet to Proxy.[/tn]
