Love letter from thief x (On Hold)

Elanor Kota was just an ordinary 24 year old girl who worked as an archeologist at a museum in Japan. When one day at night she gets kidnapped by the infamous group of thieves, called The Black Foxes. She gets kidnapped because she finds out her grandfather was Infact the Japanese Leonardo DaVinci, He was the founder of all of Japan's miraculous discoveries and inventions, unfortunately a lot of his inventions have been sold or destroyed. But before he died he left behind a treasure which was said to make any man happy, although he only left behind 3 clues to the treasure which were portraits that he made himself. To make sure Elanor doesn't run away or call the police she has a bodyguard with her 24/7 none other than the genius of the group Takuto Hirukawa also known as pork noodle boy (lol). You two don't get on at first after getting off the wrong foot at a bar, so he tries to avoid you and you avoid him too, but when spending 24 hours with eachother everyday you two get closer until fascinating things start to unfold...
