Wasn't it obvious by Asuna's reactions in the anime? Anyway, it wasn't mentioned in the anime, yet I knew it was Kirito then. When I started reading the light novels afterwards, my thoughts have been confirmed.

'''Umm.. Spoilers?...'''

''It wasn't portrayed in the anime, but in the LN Kirito visited Liz the day after Asuna did. Liz wanted Asuna to bring the 'guy she's meeting with' to her shop. The next day, Asuna had guild activities, so Kirito came alone.''

End Spoilers?

By the way, if you guys haven't read the side story for this, I highly suggest you do so. You get to know more of Liz' thoughts during the events and feel her heartaches.
