The Steve and Laura relationship is one of the relationships in the Family Matters series. Steve was shown to have an obbsessive crush on Laura but she didn't return those feelings until later. During that time, he devoted his time to Myra and Laura was finally able to have a break. When Season 9 started, She finally found herself falling in love with Steve after he got himself a makeover, but he remained true to himself. It was in that moment, she found herself confused between Stefan and him.
Meanwhile, after Laura returned her feelings for him, Steve's relationship with Myra fell apart and she was desperate to keep him from slipping away. She pretended to break up with him in order to get Steve to dump Laura, return to the sexy nerd she loved (suspenders and all) and stay with her. The plot failed and Myra began her attack by not only suing him for Alienation of Affection, but also stalking and spying on him with illegal surveillance gear and went as far as installing a spy cam on his glasses which she dubs "Stevie's Glasses Cam". She recruited Stefan in her scheme to break up Steve and Laura. Though initially successful, she still wanted to date him and Myra refuses to rest until Steve is hers. During that time, Stefan feels guilty of trying to break them up and refuses to get involved with her again. He tells Steve everything about what Myra has done and suspects she's stalking him. The next day at Myra's house, he confronts her for ruining his date with Laura. Myra defends herself, stating that he deserved better and was extremely bitter with him for tossing her aside. Steve reminded her that she dumped him first and therefore she can't harbor more feelings for him. Myra even asks him what he saw in Laura that wanted him to be around her when he has someone who loved him for himself. Before Steve was able to finally explain to her why, her mother asks for assistance. After Myra leaves, he found out the truth and is outraged with her for violating his privacy with illegal surveillance gear in her room. He breaks his glasses and destroys the cam by stomping rather hard on it. Steve confronts Myra and demands she relinquish her love for him immediately because he will never take her back since he loves Laura. She refused and dressed up as her to ruin their date at Amore's. Myra got Laura arrested for stealing her watch. However, Steve was able to get the charges dropped when he exposed her for stalking him with illegal surveillance gear in her room. The police confiscated everything and pursued criminal charges against Myra.
Laura accompanied Steve to his polka meeting and rather than get annoyed, she realises that he was the man for her after learning how much he contributed to the community through polka music. In Pop Goes The Question, Steve and Stefan both propose to an unsuspecting Laura and she goes to her parents for help. Feeling that she deserves better than him, Steve decides to pack up and move to Russia. Laura stops him by telling him that she has decided to marry him over Stefan because he was a gentleman to her all his life and would be there for her when times got rough. Whereas Stefan would eventually find a weak point in Laura, take her for granted and treat her like dirt. Steve stays and Stefan accepts their relationship. During that time, Myra learned about their engagement, makes her final push to win his love away from Laura by posing as his fiancee, to which failed to win Steve back.
A running gag with their relationship is that every time they go to dinner at a restaurant serving foreign food, they wear clothing representing that country's culture (e.g. wearing brightly-colored kimono in a Japanese restaurant, or flamenco clothing in a Spanish restaurant).

Soon Herb and Diane feels guilty about their negligence towards him and finally apologizes to Steve for what they done.
