1. Jay and Lina have a daughter and father relationship but that can also change in any case. Jay gives her a lot of love, but not only that. He also gives her a t-shirt, sweater, or other things, although Lina said that she doesn't need it, only that she he needs his hug and his loved ones but he does it anyway. Jay once says that he knows Lina best although the members disagree but we don't want to bring electricity in but there's one thing he only knows about Lina's secret, the secret is he's seen her cry twice, once where she hurt herself and once when she had no energy and no longer knew
At the moment he hasn't promised anyone to tell her, to this day everyone wants to know what's going on, but he doesn't say anything about keeping his promise unless the members know about it
