I checked out the character profiles. Adri, is supposedly Flirty and Stubborn, the stubborn part is straight forward, he won't easily give up. However the flirty part is a bit... for you to put flirty as his second main personality type, I am really curious to see a bit of this "flirty" dialogue. Adri seems already a pretty interesting main character. From what I can see so far he seems to be not easily persuaded, and can handle himself. As for Seal, I haven't seen any dialogue with him so I can't comment much about him, however I feel saying he is both childish and mischievous is a bit too much. It makes me worried that he is going to end up being a super annoying character. Is there another way you can describe his personality? Like cunning, scheming, sly, witty... Childish along with mischievous just feels too extreme of a bad boy annoying personality type. Lastly Saputra, I feel based on his short introduction and some of his dialogue that his personality shouldn't be mainly serious and ambitious. I can understand the Serious part, however ambitious is I feel more should be more of strength. From his dialogue he makes me feel he is diligent, rational, and I am guessing due to his hating of germs he is more of an introvert.
Also my very last thing I want to comment on(I promise this is the last since I got a taste of what I was looking for) is the writing style is for sure very interesting however. I notice quite a few strangely worded sentences that unfortunately kind of throws of the tone of the dialogue going on. Is there a proof reader for your project? I feel there needs to be a proof reader since some of those lines are just very unpleasant to read in English.
