After spending their first New Year's together, Yuuta and Saki grow even closer. February brings Valentine's Day and a school trip to Singapore, and in turn, new encounters and realizations. And yet, despite these special events, the pair must maintain a certain distance in order to keep their secret, and so they feel lonely even when together. What will happen when the stepsiblings, who have always held themselves in check, begin to explore a new, more selfish kind of happiness?

FROM STRANGERS TO FAMILY When his father remarries, Yuuta Asamura winds up sharing a roof with a brand-new stepsister, who is also the hottest girl in his grade! But Yuuta and his new sister, Saki Ayase, have no delusions—they both carry trauma from their parents’ difficult divorces, and they agree to keep a respectful distance. As it turns out, however, the two have a lot in common, and slowly, cautiously, they grow closer. But is the emotion blooming between them simple admiration, familial love, or something more?

HOW CLOSE IS TOO CLOSE? Yuuta Asamura is still figuring out how to interact with his new stepsister, Saki Ayase. After discovering they have more in common than expected, the two reach a comfortable equilibrium, but things start to get out of whack when Saki fails one of her exams and asks for Yuuta’s help. Then Yuuta’s attractive college-age coworker, Shiori, invites him out on a date, and Saki finds a strange new emotion welling up in her heart…Just what is this feeling?

ALL WORK AND NO PLAY ... It’s Yuuta and Saki’s first summer vacation as stepsiblings, and they’ll be working at the same bookstore! As Saki’s coworker, Yuuta begins to see a side of her he hadn’t noticed before. But after observing her new coworker for a while, Shiori makes a dark observation—if Saki doesn’t ease up and stop pushing herself so hard, sooner or later she’s going to fall apart. In order to help her, Yuuta will have to make a decision. Should he interfere in his stepsister’s life, even if it means breaking their promise?

When Saki called Yuuta "Big Brother," it looked to everyone else like their relationship had taken a big step forward. In reality, it was more like a line drawn in the sand. As their hidden feelings make time spent together increasingly awkward, the two of them explore new relationships and weigh their priorities. Are some things worth holding onto despite the sacrifice, or is it time to let go and move on?

How can they make each other happy, and where are they headed? Are marriage and children in their future, or something else entirely?

When high schooler Yuuta Asamura learns his father plans to remarry, he’s not too bothered by the idea…until he finds out his future stepmom has a daughter! Her name is Saki, and to Yuuta’s surprise, she’s a beauty who’s made a reputation for herself as an unapproachable “bad girl.” But as he gets to know her, he realizes she’s not the person everyone says she is. Could he be the one she finally opens her heart to?
