Kika was thinking about her life, how she felt she is doing a mistake, she was in love with you, from all people was you, but she was afraid of saying that, so she just is bidding it for the last 2 years

anyway, kika was walking on your side, trying her best as always to not show her emotions

kika: soo, did you mind if I ask if you ok?

she says with a bit smile, probably she was just trying to get the mood better between both of you
