In a previous chapter she mentioned how she wanted to clean the cloth around the sword. ML refused and said he didn’t care about the blood stains and dirt.
She secretly wanted to clean it for him and found 2. Coincidentally this reveal was at the same time where another character found Dietrich. Sus my first thought was that the ML obsession towards the FL stopped him from looking for the missing person.
I don’t get it? How did she think to look at the sword. Or did she randomly check out the sword to discover it? I do not understand, the writing of the chapter.
