From Chibi Manga:

Four companions are living in the same mansion. They're sharing the same school, their family, their future but also… love stories. But now, their journey to become adults is about to begin…

Rishe, the daughter of a duke, is stuck in a time loop that begins at the moment her engagement is annulled and ends with her early demise at the age of 20. She has now begun her seventh loop.

In her past do-overs, Rishe experienced various occupations, including being a merchant, a pharmacist, and a knight. But this time around, she simply wishes to live a long and leisurely life!

That was the plan, only for it to be derailed by an unprecedented marriage proposal from her killer in the previous loop, the neighbouring country's Crown Prince—?!

With her engagement annulled, Tiararose was supposed to have been exiled from the country.

“This is the otome game I played!” She realized on the day before the story’s ending.

Is waiting for my conviction the only thing I can do? But, I did not do anything too cruel... Thinking so, the ending proceeds.

However, during the judgement, something that was not possible in the game happened. Tiarose was proposed to by the crown prince of the neighboring country.

On the second morning after my 20th birthday, a miracle happened. On that day, I found out the truth: my fiance had had a hidden lover, my very own cousin. After that, I decided not to believe in love anymore, and died miserably.

When I woke up, I was in my past. This time, I want to have a relationship with no strings attached, and without any superficial feelings such as love. So I proposed a marriage; a marriage that would be nothing more than to keep up appearances, where there would be no love involved. "Duke Agentine, will you marry me?"

I'm Airi, an office worker who reincarnated as an otome game's villainess, Irene. I was on cloud nine ready to start my second life when I was expelled from the academy. With the help from the townspeople, I opened a quaint café. I was supposed to enjoy my new, peaceful life when suddenly "a fluffy creature" appeared! I tried to feed him my signature sweets, but...?!

From JShoujo Scans:

Saho, in her opinion's, lived a pretty happy life up until now with her mangaka father and a grandmother she lovingly calls "Granny."

However, their peaceful life's disrupted one day when they receive a phone call saying that Saho's mother, who had left her father years ago taking Saho's older brother with her, had passed away. This leads to Mugi, a brother she hadn't seen in ten years, coming to live with them.

Unable to stifle her hunger any longer, she crawls out of her hiding within a tiny, old, worn-down castle in search of food…

"I'm hungry," the small girl who's wearing nothing but shabby clothes murmured without even realizing, "Can I eat this…?"

"Estrella…" the child recited the name, her words one with the wind. It was a precious name that she had earned only after a long time.

"I'm sorry I'm late."

"…It's alright," the little one who replied then slumped onto Elias' chest.
