[Normally, Homura flirts well with others, man or woman, shood the mood strike. Something about this particular situation, however, gives him pause--most likely the idea that this man is flirting with the woman Homura holds most dear in the universe. Thankfully, Homura's self-awareness is still in tact, and he laughs softly after a moment.]

Careful. You could find yourself in a situation where you're uncomfortable.

[The warning is given more as a tease than actual caution. If this man isn't wise enough to prepare himself for the obvious possibilities, Homura will gladly do his part to make the situation worse.]
