@Taylah swifcht I understand where your uneasiness comes from. I never felt this way though, because Tei never developed attraction towards Shuraka in the past. He always acted as a protector, and as an older brother/dad, in the way he cared about Shuraka - hugging him to offer safety during the night, telling him stories to help him fall asleep, teaching him how to use a sword, being loyal - he deeply cared for Shuraka, and his feelings were pure. He was convinced that Shuraka would, one day, take a woman as a bride, so his behaviour was truly selfless. Shuraka, on the contrary, developed deep attachment, but he considered Tei as his own bride, since their first meeting. This is not strange at that age - 9-10 years is enought to have a girlfriend, according to my nephew 😃 - The author here walked a treacherous path showing this pure, mutual love, but he did it beautifully because he portraied what the two characters felt, based on their age and expectations, never crossing the line. Now that Shuraka is an adult, of course the dynamics shifted from pure to physical, but since they are both fully grown adults, I feel pretty comfortable in their romantic relationship.
I love reading webtoons and collecting manga.
