@OwO-sama I don't think it doesn't portray the feelings of the MC, but I agree that the light novel does a better job at it. I think you have this feeling because you came here after reading the LN first, but the thing is a manhwa can't possibly portray feelings as good as a LN. Words are always better at portraying feelings than drawings, because you can take your time to do a long description. But if you do the same thing with a manhwa, it'd kill the flow and people will complain that it's too slow. Like the scene from the previous chapter, when he finds out his sister is being attacked while in a dungeon : in the LN he panicks realizing he can't use soul transfer because of the cool down, and the scene feels emphasizes on his train of thoughts. But if you tried to do the same in a manhwa, then it would feel as if there is no progression and as if the chapters are getting slower. There are tons of manhwas out there that focus on the thought process of the MC and all, and... most of them are quite bad tbh, because the pacing feels too slow.
But on the other hands, the fighting scenes feel WAY better and WAY more dynamic in a manhwa. I've always felt that LNs do a terrible job at creating good fighting scenes. That's why I think both supports have their own advantages and disadvantages, and I don't think comparing the two really is a fair comparison. The manhwa will focus more on the action scenes because that's the strong point of manhwas, and the LN will focus more on the feelings/train of thoughts because that's the strong point of LNs.
