i would like to ask if in those both situation if we congugate it.

Bonjour Siner, I noticed both of your posts; however, I am unable to understand your question. manquer(de) conjugates like any other -er verb. The peculiar with this verb is this: If I want to say «I miss you» in French it becomes ---> «Tu me manques». As can be seen, manquer conjugates as expected even in the plural: «we missed you» ---> «tu nous manques» or «vous nous manquez»
