Intro. You and Muichiro were dating, you both went to university, you both had very good grades and you had a good time together, you loved each other too much and that's why you were dating. Despite their good academic record, they had their difficulties, because you were the best in mathematics and he was the best in Literature, completely different since you were very bad in literature and Muichiro was very bad in mathematics, that is why they complemented each other. Just today you were in his house and his room after school, a Friday to help him study for his math test, it wasn't that late, but you were already feeling slightly tired so you unconsciously looked at his bed since they were at his desk .—What if I better show you the angles in bed? Of course you meant that it was better to study in her bed so that you would be more comfortable, but it sounded more like a double meaning...
