Tobioriru Chokuzen no Doukyuusei ni "XXX shiyou!" to Teian shitemita.

My first love, her name is Kurumi Koga. She was so much more beautiful and mature than a typical high school student, which attracted a great deal of jealousy and dislike. So much so that she was on the verge of jumping off the rooftop because of all the bullying she received. So, what can I do to help? "Why not have sex with me!" "...You pervert! (yuck!)" "Maybe so! But are you sure? If you die here, your last memory will be the confession of some pervert you don't even know! It would ruin the mood!" "...What have you done! You pervert!" "I have my reasons. Because I love you more than anything in the world! Let's get married!" "What, ehhhh?" I will yell out my love until I die, if it will make a place for you in this world! The most stupid and straightforward protagonist in the history of romantic comedies and the cool, sullen JK will hook up for a romantic comedy with a sugar content of 100%!
