This series reminds me of "We Without Wings/White Angels Without Wings". (forgot the exact title) The difference is that the pale-haired girl in this series is the antagonist. Also the s2 plot is such a healing, nourishing oasis after the hurtfest that was s1... I kinda dread what's gonna happen next, but I also look forward to it.
Many thanks to the translator, the quality is rough but serviceable... Doing that while not knowing Korean is impressive to me. (✨TECHNOLOGY✨) When I read translations like these I wish I could help put on the grammar front at least. Wish I had better internet, can't even open Mangadex fast enough. T^T
