@nep iirc in the WN version, the suicide scene was in the throne room. The soldier who invaded her country never told anything about disgracing her or whatsoever. At that time she was in so much despair she shut her heart and simply gave up on living, so she
froze (immobilized) that soldier and borrowed his sword to stab her heart.
I mean, I remember clearly the soldier (in WN) said something like "please surrender" and never tried to do anything the one in this manga did.
