Shinjiro's Girl
Increase your academic, charm and courage ratings. These three ratings will raise your social link score. The higher your social link score, the better chance you have of wooing any of the potential boyfriends.
Speak with Shinjiro at every opportunity. The more you speak with him, the more you will raise your connection level with him. After October 4th, in-game time, you can begin dating him if you have spoken with him every time you could.
Continue to speak with him when he's confined to a hospital bed and confess that you love him when given the opportunity. Dissuade him from putting himself down and continue to choose dialog options that show him you care about him. Eventually, he will confess that he loves your character as well. This will keep him alive.
Akihiko's Girl
Maximize your charm, courage and academic scores to max out your social link score. This will give you an advantage with Akihiko, who is a little more difficult to pursue than Shinjiro.
Speak with Akihiko at every opportunity. Choose only flattering dialog options.
Select the three vital dialog options. Most of the time, simple flattery will raise your connections with Akihiko. However, three instances occur in which you must choose certain dialogue or you will never have the opportunity to be Akihiko's girl. When he says, "Oh, no, it was just a rumor I heard. Sorry," reply: "Don̵7;t get the wrong idea, Senpai." When he later says, "Do you think I̵7;m...strange?" reply: "You're charming." Lastly, when he says, "...It̵7;s the weirdest thing," reply: "You're in love." This will prompt him to ask you out.
