How should I interpret this に?


> お前の姿 **に** 瓜二つだからこそ、むしろ許せない…！

Is it something that goes along with だからこそ and therefore means "because"? I
know that this is one of the meanings of に but I'm not sure if this is the one
used in this case since だから already expresses the idea of "because.."




Coming after 姿, the に functions as the same way as it does in ～にみえる and ～に近い.
Basically 'in relation to ______' or colloquially 'as'.

だからこそ does indeed function as 'because' or 'especially because'.

瓜二つ is like saying 'Two peas in a pod'. I.e., having the same appearance or
form as another.

そのおばは私の母に瓜二つだ - That lady is the spitting image of my mother.

そのおばは私の母にそっくりだ - [Same meaning as above]

Broken apart: お前の姿(Your appearance) に (as) 瓜二つ (strikingly similar) だからこそ (For
that reason/that's why) むしろ (rather) 許せない (not forgive).

Rather literal translation: [He/She/It] has identical appearance to you.
That's why I'd rather not forgive [you]!

Attempted figurative translation: I really can't let it go because he looks
just like you!
