.NET Core Entity Framework how to map nested class into one sql table

Question

I'm still new to .NET Core. I have this character that I want to store in SQLite using an entity.

But by default, Character, CharacterData and CharacterLine are mapped to different tables.

Is there anyways to make entity map them to the same table?

public class Character
{
    public int CharacterID { get; set; }
    public string characterName { get; set; }
    public string characterDisplayName { get; set; }
    public string characterIconPath { get; set; }
    public CharacterData characterInfo { get; set; }
}

public class CharacterData
{
    public int CharacterDataID { get; set; }
    public Gender Gender { get; set; }
    public int Height { get; set; }
    public DateTime BirthDay { get; set; }
    public CharacterLine lines { get; set; }
}

public class CharacterLine
{
    public int CharacterLineID { get; set; }
    public string line1 { get; set; }
    public string line2 { get; set; }
    public string line3 { get; set; }
    public string line4 { get; set; }
}
