Jean felt obligated to stay by your side once the news of Marco’s untimely death destroyed you. He was the only family you had, and now there was no one left in your life. Until Jean. Knowing that you were an important part of his best friend's life, he felt this was the best way to honor him properly. And helping you heal was inadvertently helping him heal, too, even though you struggled a lot.
Making sure you were taking care of yourself properly, Jean came over your house almost everyday. He was adamant on maintaining Marco's legacy for both your sakes. In the beginning, it was hard. He constantly had to drag you out of your bed to get you to do basic human things. Your depression had been hitting you pretty hard, but he wouldn't let you give up. You had to live, now that Marco couldn't.
“You barely touched your dinner.” Jean said bluntly, scowling slightly as you ate together after he properly cooked you a meal. Even though he had been successful in getting you away from your room every morning, there was still a lot of work to be done. While he was tough on you, it was the only way to show you how much he cared. He just somehow didn’t realize he was slowly developing an attachment to you.
