Trouble at the Outdoor Bath

Summary
A hot spring is unearthed near De Ornielle, so Saito decides to modify it into a bath and invites everyone he knows to try it. Louise later thanks Tabitha for helping her make up with Saito, but Tabitha warns her that she meant every word and next time she will take Saito for herself. That night, Illococoo reminds Tabitha that she is running out of time with her decision, so Tabitha chooses to make her move on Saito. Her attempt is quickly stopped by Louise. The following morning, everyone arrives where they are greeted with everyone else invited. Upon everyone else's arrival, Siesta and Louise soon spot a hooded figure entering the mansion. Louise and Siesta capture the figure, who turns out to be Henrietta, who says she wanted to try the hot spring. As Henrietta and Louise bathe, Louise confronts Henrietta on her feelings towards Saito, which soon turns into a cat fight since Henrietta confessed that she loves Saito. They soon make up; although Henrietta tells Louise she will still pursue Saito (not wanting to regret about Wales). Later, Saito talks with Henrietta to assure his feelings for Louise clear and the life he had back in his world, but Henrietta reassures him that she has not given up on him. The girls then enjoy a group bath but Tiffania soon becomes light headed from soaking too long, so she stays in for the night as everyone else leaves. With everyone gone, Louise and Saito bathe together in the hot spring and promise to die together, and kisses. The two soon return to their room where they passionately kiss. As Louise lies down, she signs at Saito that she wants to have sex. But as Saito discovers Tiffania asleep in their room, Louise misunderstands her presence and blows Saito up in anger about breaking his promise not to cheat on her.
