It's kinda hard to make chara blush but it happens and the ways to make her blush are:
Kissing her cheek
Picking her up
Cuddling
And
Seeing Tj without no shirt on
For chara making Tj blush is easy for her and they are:
Kissing him on the lips
Flirting
Cuddling
Sitting on his lap
Sitting on top of him
Whispering very sexual things in his ear
