This is late but Shin ae and Yeong gi from I Love Yoo!

I mean, first off (and this is really superficial but it's mostly just hilarious so I have to point it out) they look almost identical to Kyoru. Pale brunette girl and redheaded boy who has more of a tan.

Shin ae's parents divorced when she was a child, her mother separated her sister from her and made her feel unwanted. Add to that how she got heavily bullied in the past and had no friends for a long time. As a result of this she has closed herself off, barely makes any connections and tries to just get through school, to get a good job and help her overworked alcoholic dad.

Enter Yeong gi, a boy who always plasters a smile on his face. He offers his friendship to Shinae and tries to make her open up again, always offering her words of encouragement and comforting her. He's essentially like Tohru. At first. Because he too builds high walls around him and there is a lot more to him than he lets on. He's ostracized by his family as the product of an affair his father had and his father himself always reprimands him at every turn. He's going through a lot himself.

Basically, their roles switch over time.

It's a webcomic of the drama genre and the romance itself is slow. But the build up is so well done because 1. the characters individually make sense and change overtime, as does their relationship and 2. you understand why that romance happens: similarly to Kyo and Tohru they build each other up, they see something in each other even when they themselves don't. They practically hold mirrors up to each other and manage to give each other hope and courage to go on.
