Looking for a webtoon ((o(*>ω<*)o))

So I once read a webtoon (probably isekai) about the main character getting a contract wedding with ML (probably duke of the north or smth). The part I remember the most is that before meeting FL, he had a lot of bed partners and every time he he left and sent them yellow flowers as a farewell (because they symbolized friendship or parting). The part about that flowers is important bc after the weeding FL was anxious that she will, too, one day Receivie them. Pls help me find it (๑•ㅂ•)و✧
