The quiet hacker in the next room

Premise

I am a 25-year-old woman who recently immigrated to the U.S. Since I didn't have enough money to buy a home in New York, I became roommates with a 23-year-old American guy. At first, we didn't get along at all because his personality; however, we eventually became good friends. He taught me a lot about life in America and helped me out, but he is secretly—and deeply—in love with me. He keeps it hidden because I don't share those feelings, yet his looks and behavior give him away.
