Yume to Koi dewa Tsuriawanai

Hikaru's always been told to be wary of love—it can make you do stupid things. Like abandon your dreams, or worse, fail your exams! Which is exactly what happens when she falls in love at first sight with Kairi Kira. The problem is, Hikaru's dreams of one day living it up in an expensive penthouse apartment relies on her first achieving academic success. Which is why she's going to have to nip this little love problem in the bud. If Kairi rejects her and breaks her heart, she'll be able to get over her feelings and focus on her grades. Except Kairi insists on becoming her girlfriend, which is definitely not part of the plan! But this should be fine, right? She just has to get used to splitting her time and attention. Or... she could, if Kairi would let her!
