Sorry, you must re-read it, maybe chapter 65-69. Sakura asked Shinobu why he wants to make her dream comes true and he replied because I love you. She then cried with happiness and replied indirectly that she also wanted to be with him. Later, he asked for her answer to his confession again for a clear meaning, she then cried again and said she also love him too.
They show us they're in deep love. That's why we get angry in chapter 129 and 130 that Sakura suddenly changed her boyfriend just because the fucboy's endurance (can have sex till the morning). So, the deep love they shew us the readers is fake?
Pal, please don't behave like Airi Katsura (sensei) who forget what she wrote in the former 128 chapters. LOL
