Summary:
After the two of them escape from Charlotte’s over-protective butler, Charlotte reveals to Teppei that her foot is hurt, and he decides to carry her to the infirmary. Charlotte uses the chance to get Teppei to promise to take her to eat at a place his family owns, but in the meantime, their attention is turned to the sudden parachute arrival of a man named Hartmann Bezelheim. Sylvia recognizes him as a businessman from Hazellink, and everyone, including Sylvia, is surprised when he introduces himself as Charlotte’s fiancé. Hartmann plans to stay for a while and has some business with Teppei’s grandfather, and after he leaves the school grounds, Charlotte doesn’t want to talk about her engagement. Teppei acts like he doesn’t mind though and still wants to take her out to eat. Later that night, Sylvia overhears her father talking angrily on the phone about their home country, and she confronts Charlotte about it the next day. As it turns out, there is a secret nuclear weapon storage facility being constructed under the border between their two countries which could threaten their countries’ relations, but Charlotte claims to know nothing about it.
Afterward, Charlotte gets a text message from Teppei saying that he wants to talk with her tonight at the Arima Hills location that she wanted to eat at. Teppei goes there in person to make the arrangements, and while he’s at the front desk, he runs into Hartmann. Hartmann just wanted to greet him, and while Teppei is away from his phone, he misses a call from Charlotte. Hartmann then goes on to meet with Teppei’s grandfather and Sylvia’s father about the situation regarding their respective countries. Charlotte meanwhile gets another text message from Teppei telling when and where to meet, so she sneaks out of home and heads there. The room is empty though, and Teppei is actually back at his house practicing with his sword. When he gets another phone call, he realizes that he’s been missing Charlotte’s calls all night, but when he tries to call her back, no one picks up. Shortly thereafter, he gets a text message referencing what happened to his parents and threatening the person who loves him. Unbeknownst to Teppei, the power at Arima Hills has been cut off, and a force of armed men have arrived.
