Getsuyoubi no Maria

Maria, a Lehman who is a sharehouse resident and receives an ardent love call from Hikaru, a high school student. On the other hand, while he is a straight confession that seems to be a high school student, he is swayed by Hikaru because he is not shining or honest... The same is true for Maria who cannot be obedient, and as soon as he reexamines his feelings, things change one after another...!? Where is the love of the two people?!?
