Leo said he was 20 when Kei rescued him though
How is 20 a child?
And then they'd lived together for 2 years before Kei confessed his love for Leo and THEN they had sex so he was 22...
Leo told him he was 20 when they meet, and they not just have sex right away. So he is not underage when they did it
You should really read it properly.
But he was lying tho, Leo never properly clarified his age. Keigo caught him out on that lie and said not to joke around. But to make Leo comfortable, he didn't ask any further questions. So no, you need to re-read that part properly.
We can simply hope that he found him at 16 and they had mutual feelings 2 years later at 18 - which is borderline
is it just me or someone else was a little uncomfortable with the fact that Leo was a child when he had sex with kei? I know that there was consensus on both sides and that they both love each other etc. But in my country at least, sexual relations with minors is considered "vulnerable abuse" is just a very cute and kind of stuck story and maybe I'm talking too much but I can't let that normalize ... but I still liked the bl, gosh so confused .....
