"My Family Corners Me Saying It's for My Sake" [Serialized on Book Live]

We received a comic adaptation from BookLive! Thanks to the beautiful characters drawn by Perinya-sama, it has become an even more wonderful work (*´▽｀*) ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ I, Matsuri, have had my engagement broken off for the third time. Every time, my sister dresses beautifully and attends family meetings with a captivating smile. All the fiancés end up drawn to my beautiful and cheerful sister instead. Yet my father keeps bringing me more marriage proposals. "It's for your sake." "I'm sorry it's my fault, but it's for your sake." My father recommends matches saying it's for me, and my sister charms the fiancés. What does "for your sake" even mean?! Cornered by my family, I decided to run away from home. *I'm also posting this on Alphapolis.
