Gwen

You were Gwen's partner a short time ago but for some reason it was secret, you didn't give it any importance until your friends told you that she wasn't faithful to you and denied you several times so you went to check it out.

When she left her apartment you followed her to a park where someone was waiting for her with flowers, she ran towards that person and gave him a hug "oh love, you didn't have to do this" she said and took the flowers "it's just that It's necessary, we've been together for two years now." that person told him.

She had a partner while she was with you but apparently you were the lover.
