"If you ever fall in love, do so without reservation, or rather, if you should fall in love simply give no thought to any reservation." - Vincent van Gogh Part one of two of "Love Without Hesitation". When Y/N L/N's eldest sibling and only sister is proposed to by a work employee to her father, the rest of the Y/L/N family is finally introduced to the family of Y/F/N's business partner, Alexei Shostakov. In preparation for the wedding, Alexei's family happen to be more frequent in interactions with the Y/L/N family--And it's during these interactions that Y/N takes notice of peculiarities in Yelena's behavior, towards Y/N specifically. During unnerving interactions and unclear advances, Y/N notices Yelena's boldness in behavior to be not only abnormal in behavior for people their age, but untranslatable in motive. As Y/N decides on taking Yelena's ambiguity into account as something to figure out, her brother also decides to take his speculations into further investigation--Both Y/L/N siblings becoming more serious about 'figuring out' the family.
