In 2020, Louisa Mak (麥明詩) was rumoured to have a pilot boyfriend named Keith Shing (盛勁為) but both clarified they were good friends. Lately, they are discovered to have a picnic together at West Kowloon and resemble a couple.

During the recording for the show, Cantopop At 50 (流行經典50年) on 24th February, Keith explained it was normal for friends to chat and eat together. Asking if any chances for developments, he reckoned there was a possibility and did not make the first move until now: “We feel shocked that somebody takes photographs of us secretly and might keep a distance from now onward.”

As Eric Tsang (曾志偉) returned to TVB as senior management and Sandy Yue (余詠珊) had an internal transfer, Keith replied he joined TVB through See Me Fly Again (衝上雲霄大選) show organised by Sandy: “Company restructuring is not within my control and I will focus on doing my duty well.”
