@Lilliwyt You probably already got around to rereading it some, but what I took from it is Maekawa explained she was jealous and that basically she loves Shimizu, and Shimizu reiterating that she loves Maekawa. They both share that they love each other in somewhat different ways, and Maekawa admits she's possessive while Shimizu admits she is happy that Maekawa wants her attention. Oh, and apparently Shimizu is a top while at this point neither of them care anymore if someone catches them wrestling.
This is 3 months late, but I felt compelled to give my take on the situation in the hopes it provides some clarification, if not for you then for whoever happens across this comment. Just my own personal understanding, though, so take it with a grain of salt.
