And if a teen has became friend with a YA, the teen can carry a torch for the YA(called "crush" in game, likes "woohoo" and "mess around"). The teen can chooses "Crush on…" in romantic interaction. The teen can "Expression of crush", "Give romantic gift", "Gaze", etc. , but YAs can't has romantic relationship with teens. If they knows a teen is carry a torch for them, they will has happy(romantic trait more possible, unflirty can't) or playful or tense(unflirty or noncommittal or has stable relationship must) or embarrassed(has stable relationship must) mood. The YA can "Talk about crush", "Ridicule crush", Indicate stable relationship(if has stable relationship)" to the teen. If ridicule crush, the teen will has sad or angry mood, if indicate stable relationship, the teen will sad(the mood will stronger if has jealous trait).
If the teen finally has stable relationship with the YA, the teen will has stronger positive mood(expect noncommittal). If theirs relationship is deterioration, the teen will sad or angry.
