I think it'll take a lot of time for them to properly communicate, and make the other understand their thoughts. Honestly, I love that Tei is not instantly feeling love on a partner level, and sees himself as a kind of guardian. And also love that Shuraka is not some green flag, who understands Tei perfectly and won't push him too far until he allows it. I'm pretty sure Shuraka most likely will say something that will most definitely make Tei distance himself very badly.
I believe real life relations our rarely, 100 percent green. For you to be a green flag, you need to have seen or felt that kind of relation. I'm pretty sure Shuraka in the middle of war, succession battle etc was not in a condition nor did he have anyone he considered trustworthy enough to nurture a relation with
Thank you for reading my rant. I wanted to type it as I feel like people are too hung up on wanting Shuraka to be green flag, not taking the environment he grew up into consideration. He'll surely make a lot of a mistakes regret, fix it, grow and realise that love isn't as simple as he thought it was.
Bro is cooking out here geez
