i went deeper into the comments and some people are giving so much hate to Kaoru but ?? do you even understand what immediately cutting off the string after telling him would have meant for his mental state? This is not something light, it was a FATED partner. All of Kaoru's past people who left him to be with their partner,, were they evil people? No. They were just normal humans. So how can he believe that he would do the right thing by cutting of Hara's chances to be with something like predetermined destiny so easily?! He wasn't testing Hara, he was testing fate. Before this, even though Hara reassured him of his love, the situation hadn't come to what it came in the past with him for his lovers. So how should he know whether that love will hold up in face of the fated person appearing?! Plus its easier to be in Haras place and say something like ‘Cut them off’ but to carry the burden of making that decision and cutting it off by your hand is something so much tougher. You're taking a chance at happiness from someone you love so much. Will it feel easy to do? I'm so insecure so I felt even sad when Kaoru progressed and did it because I wished he wouldn't have had to take that burden on his head. But wow, wow some people are hating on him because he didn't want to be the one to take Haras fated person away from him. And he even saw Aratos story where the string kept connecting and fated people really do fall in love. He's had nothing but that around him. How can you hate on him? I feel really crushed that such sentiment exists. I just think he's so so brave. And lovely. Sorry this got long.
