Summary
Mafuyu was a medical student. She should have known better than to be reading an unrealistic fantasy novel when she should instead be studying for her exams. Was it not too cruel a punishment to teleport her into said novel though? Stranded in Hinomori, a land where the technology lagged hundreds of years behind the world she had previously known, Mafuyu's only hope of survival was to cling onto Shizuku, the princess whose life she had inadvertently saved on her first day there. But was their encounter really a mere coincidence? Or was there a deeper reason for their intertwined fates?

Summary
“I appreciate Hinomori-san’s feelings, but I do not quite understand what romantic love is. If you are okay with this, then I do not mind entering a relationship with you.”
That was what Mafuyu said years ago when Shizuku confessed to her on the eve of their high school graduation. She naively thought that Mafuyu was just new to romance the way she was, and that with time, they would come to love each other.
Turns out that she was wrong.

Hinomori Shiho is convinced that her sister's existence is to give her a headache - she is used to Hinomori Shizuku frying their home electronics, getting lost in their neighbourhood and then begging for help, and hugging her so tightly that she can hardly breathe. Lately, Shizuku seems to have become more independent though, for which Shiho should be glad, but there is no way that her sister would have just started developing basic life skills at her age, right? Who has been helping her instead of Shiho then? Who has she been glomping instead? Shiho has a feeling that she would be getting a sibling-in-law very soon, and she has no idea how to process the news.

Summary
"Dr. Hinomori Shizuku" is a pretty big name in the novel study of Q-radiation. Setting aside rumours that she has broken three plate readers and a confocal at her last job, she has such a high H-index score that it shouldn't be much of a problem for her to land a faculty position at an Ivy League institution. But for whatever reason, she has decided to join the private Hatsune Miku University instead, known throughout the country as a college of misfits. As her new next-door office neighbour, Prof. Asahina Mafuyu can care less about Shizuku's career choices - she already has enough to worry about with her grant proposals being rejected left and right when her tenure review is just around the corner. But when Shizuku suggests a collaboration with her, she hesitates. Though the suggestion would solve all her financial problems, is it worth the risk of becoming an outcast in her field?
