here, means: "spending quality time together" Or, "speaking to each other" bond: a close connection joining two or more people

I cannot see the context here, however... Bonding is the formation of a close human relationship, as between friends or the emotional and physical attachment occurring between a parent or parent figure, especially a mother, and child, that usually begins at birth. Bonding can also mean the joining of 2 surfaces together as in glueing... Hope that helps?

Bondっていうのは「絆」です。"Bonding"は「絆をつくる」となります。
