The way the manga is written is… weird. Her feelings could be very easily infered by her backstory, but the author had to show us her inner monologue just to make sure we understand.
I remember reading the WN a long time ago, but the TL took so much time between releases I just dropped it. I even got notified from their own discord server each time the raws updated, and at that point it seemed like the manga would never catch up either. Glad to read this story again
