Marisa Kirisame ---Love--> Patchouli Knowledge Marisa Kirisame ---xNo...--> Alice Margatroid
Looks like Alice was rejected for Patchouli, and refused to take "no" for an answer more than Marisa two-timing, at least this time. (Which explains the lack of outrage on Patche's part, as well.)
Also, this artist has a lot of good images on this trio.
