Ex-Boyfriend
     Well, this relationship should be rather obvious. In tankoubon 13, Mako-chan has a dream about "senpai". "It is very common for people to dream about ex partners. Individuals that have been an important part of our lives, continue to take up a part of our mind and heart. It is impossible to very dramatically shut the person out of our thoughts and feelings. Just because the relationship ends, does not mean that all is finished. As we go through relationships, we learn, and at times pick up "battle wounds". You will continue to dream about your ex-girlfriend or boyfriend until you "let go" of them on a very important and deep level, or until you learned your lesson from that relationship. Either way, dreaming about your ex-romance does not predict future involvement. It may be wish fulfillment, reliving memories, or working out old issues. Dreams are very rarely prophetic." Mako-chan may still be connected to her senpai more strongly than she thought. She may still think she loves him, but perhaps she is trying to heal herself, without knowing it.
Fighting
     While she may not dream about it, Mako-chan certainly does fight. "It usually symbolized anger and confusion which comes about in times of change. If nothing is changing in your life, it may be a clue that a change is needed or that you trying to change internally." Her life is always changing...she is a teenager.
