Days With My Step Sister Gimai Seikatsu Volume 2 Mikawa Ghost by Mikawa Ghost instant download after payment.

The siblings' feelings, unfamiliar emotions, the blissful days continuing with them slowly getting used to each other.
As a result of his father's remarriage, high school student Asamura Yuuta ends up living together as brother and sister with the number one beauty of the school year, Ayase Saki. Despite them clearly not used to spending time together with same-age members of the opposite sex, their distance to each other slowly shrinks, as they realise how similar in personality they actually are.
However, as the regular exams roll around, a change in Saki's behaviour becomes apparent. Worried about Saki, who is dealing with certain subjects she's bad at, Yuuta decides to become her support. Creating a beneficial learning environment for her, or searching for music that allows her to focus better, Yuuta concentrates on offering as many ideas as possible.
At around the same time, Yuuta is invited out on a date by his charming senior at work, the girls university student Yomiuri Shiori. What is this mysterious 'emotion' that starts to rise in Saki's heart as she hears of this?
