Hello,
Less likely, but possible.

A visible cold sore may or may not be an ‘active’ cold sore. The chance of transmission is high if the lesion is active and shedding virus. Unfortunately there is no easy way to know this. Let’s assume the worst case scenario (that the lesion was active) still you have less chance of contracting it because the kiss was on the cheeks. Herpes transmission is high through mucous membrane and abraded skin, and less through intact skin.
Now let’s assume you contracted the virus, even then it is highly likely that you already had the virus in your system (Around 50-60% adults are seropositive for HSV). Even if you had contracted the virus, chances are that it will never manifest (and you will join in the 50-60% seropositive pool).
So putting all these together – it is indeed less likely that you had contacted HSV and very less likely that you will ever manifest cold sore.

Hope this helps
Please feel free to ask followup questions.
Thank you.
