Romance seems kind of one sided, the boy overheard that she was programed not to fall in love. After the home stay she has to go back for a memory wipe, during a final outing at an amusement park the boy asked her to runaway with him, but she refused. Time passes, there is a school reunion female friend is married, everyone but the MC has moved on with their lives. Then he sees the robot girl working as a pre school teacher assistant. Of course she doesn't remember him, but some how she remembers a song from their time together. The story kind of ends there.
