Giving Frozen Tears to Kuro I'm on my first run ever of the game and have just received frozen tears from the Divine Child to give to Kuro. If I give the tears to Kuro to drink, does this remove the possibility of getting the "normal" ending? I plan on starting a NG+ after this, but am not sure as to which ending is best for first time players

Also currently, I'm stuck on Owl(Father) in Hirata Estate and just defeated Corrupted Monk in Fountainhead Palace
