That can make things hard. The being heard part. I used to tell Marinette all the time how much I loved her but when I was dressed like this as Chat she never took it seriously. She was in love with Adrien Agreste and anything Chat said to Ladybug registered as a silly flirt.

[He shook his head with a little laugh.]

I don't know the best way to make sure but I can offer a suggestion. When you decide to tell her take her hands in yours, make eye contact. Tell her there's been something serious you need to tell her. Emphasize that it's serious and that it's the truth.

Tell her that you love her and the time you have together, the laughter, the banter, how you get along. Then tell her what you want. Tell her you want more - dates, dinners, dancing, a relationship... Be as direct, raw and vulnerable with her as you can.
